4K3, 604 986 8737 Development of Delta Pair Combustion Engine lntroduction:
The combustion engine, diesel or fuel fired type, works insofar with two principles, four strokes operating sequences or two strokes operating sequences.
Engineers have been working for century in order to improve the performance of the combustion engine. However it has become very advance table, what the technology has now achieved on the both principles of conventional combustion engine. High speed and high performance engine but efficient fuel consumption is now widely implemented in the automotive industry, power generation, ship industry etc. The basic remain the same.
It was Prof. Wankel, who has made the break through in the 60s with his invention of Wankel-Motor (engine). This rotary combustion engine operates with the same principle of four strokes engine, but with considerable high performance due to genial and remarkably balanced rotary piston design. However it's implementation as prime mover in the automotive industry and power generating equipments has not beat the market of conventional 4 strokes engine. Other similar rotary engines have been developed but so far these engines are not yet feasible for production.
The four strokes engine runs 2 circles to complete the process, while the two strokes engine needs only 1 circle. Meaning the 4 strokes engine loss it's energy for 1 circle turn comparing with the 2 strokes engine. But in fact 4 strokes engine produce more power than two strokes. Despite of advantages and disadvantages of both typed engines, 4 strokes engine are widely used for universal prime mover.
It has never been thought, that 4 strokes engine can be combined with the 2 strokes engine as integrated unit. The combination can eliminate the disadvantages of each type and the unit will produce more power. Minimum number of combination is 2 pistons (one pair), consists of 1 piston of each type, each piston has it's own crankshaft but not the inlet and exhaust valves.
The arrangement of cylinder liners conform a triangle formation or delta ( ~
), this will enable the one crankshaft to be connected to another crankshaft by gear system. The ratio of crankshaft speed shall be 2 : 1. The construction of cylinder head shall be integrated for both pistons and include the arrangement of inlet and exhaust system. It is foreseen that the cylinder head has a window to stream out and in the gases between the both piston chambers.
The idea is about to utilize the exhaust piston rising of the 4 strokes engine half to push out the hot gases into the exhaust valve. Heat energy still remains in the compression chamber of the 2 strokes engine half, which will be mixed with air-fuel mixture in the next induction/charge sequence by the both pistons. The speed of 4 strokes piston is double so high than the 2 strokes piston, even though the compression will be made at the same time by the both pistons. When the pistons are nearly at the top, the sparks flare and the expanding gases drive the pistons back down for the power stroke.
It is expected that construction of the delta pair engine will result remarkable fuel consumption, better dynamic balance condition, high performance engine and remain easy for maintenance. Furthermore the use of wasted heat energy for the compression and combustion is a kind of afterburning in the yet engine, which will result not only a great response in accelerating the engine speed like in the 2 strokes engine, but also in lowering the fuel consumption remarkably as well as the reduction of pollute gases. A contribution to maintain the good environment condition.

4K3, 604 986 8737 Detail description Engine block Engine block, where piston liners are located, is to be designed so, that the centrelines of both piston's movements on the top side come to a point, a top point of an triangle (delta), whereas the bottom side points of the triangle are conformed to the center points of the crankshafts pair. The distance between the crankshaft center points depends on stroke length. The cylinder liners shall be construed on the top as close as possible, however it shall not disturb the waterways for effective cooling. The liners of the delta engine can be a bit longer the conventional high speed engine due to the fact that the 2 strokes compression sequence starts when the piston is in the middle of the liner during piston rising.
The delta engine block is bigger and stronger in the bottom side, where the both crankshafts are mounted. The oil sump of this engine becomes also bigger.
Pistons for delta engine have specific design, since the connection between cylinder block and cylinder head shall be flat and horizontal, top surface half of the piston will be cut in certain angle accordingly.
Connecting rods are mounted to the crankshaft with metal bearing as usual or roller bearing for small engine.
If the crankshaft of the 4 strokes engine half is designed to turn in the clockwise direction, than the other 2 strokes crankshaft for optimal balance operation and simple gear connection shall be in opposite/ counter clockwise direction. Ratio of transmission must be conformed to the 2 cycles for 4 strokes and 1 cycle for 2 strokes engine half.
Flywheel for the delta engine is a unique part, which can be mounted on the high-speed crankshaft of the 4 strokes engine half. Since the transmission gearing of the crankshafts has potential mass, the weight of the flywheel can be reduced.

Flywheel for the delta engine is a unique part, which can be mounted on the high-speed crankshaft of the 4 strokes engine half. Since the transmission gearing of the crankshafts has potential mass, the weight of the flywheel can be reduced.
2. Cylinder head is designed minimum for one pair or two pistons engine. The construction is basically the same as conventional engine. Combustion chamber of one cylinder has a channel to another cylinder. The channel is designed specifically, that the stream of gases from higher pressured chamber go to the lower pressured chamber smoothly and finally forced out the product of combustion into the exhaust channel Intake valves is/ are placed on the 4 strokes engine half only, it will enable to bring the fresh air as much as possible and than distribute to the 2 strokes chamber during compression stroke. The opening of the inlet valves must be determined so that during intake stroke of 4 strokes piston, the exhaust valve/ s is / are completely closed.
Heru Santoso Dipl.-Ing., 2683 Tempe Knoll Drive, North Vancouver, B.C., V7N
4K3, 604 986 8737 Due to higher speed of 4 strokes piston's down movement, more fresh air comes into the chamber, only a part of gases remain in the 2 strokes chamber. The compression stroke of 4 strokes piston starts from the bottom dead center (BDC), while the 2 strokes piston starts from the half stroke of upward movement. The fresh air will go from 4 strokes chamber through tinny top channel into the 2 strokes chamber and mix with remaining hot air in balanced condition (pressure and mixture). When the sparkplug flares, the power stroke will begin.
Exhaust valves is/ are located on top of the 2 strokes piston chamber. The valves is/ are opened only during exhaust stroke. The exhaust pressure is generated by the 4 strokes piston upon upwards movement, while 2 strokes piston still moving downwards slowly. It is advance table to release the gases as quick as possible through 2 exhaust valves opening, and close immediately when the 4 strokes piston starts to move for intake stroke. It can be further developed that one of the exhaust valves delays the closing in order to release the hot gases into the exhaust at least for a quarter displacement of upwards movement of 2 strokes piston without streaming the hot gases in to the 4 strokes chamber during fresh air intake.
Overhead camshaft is driven by the crankshaft through flexible timing belt, depending on the valve arrangement, single or double overhead camshafts can take place.
Spark plugs is/ are foreseen for gasoline engine with conventional fuel metering system (carburetor) as well as with fuel injector nozzle. Spark plugs is/ are mounted vertically at closed position to the channel of combustion chamber.
Double spark plugs assure better burning on both combustion chamber. For diesel engine, fuel injection nozzle will take the same place where the spark plugs are.

3. Intake manifold, Exhaust manifold, Fuel supply system, Starting motor, Water cooling/ air cooling system are not different to the conventional engine. The inlet and exhaust manifolds are designed separately on each side of cylinder head, these give more space for smooth channel form and lowest friction of the air/ gases flow.
Since the cylinder block is smaller on top ,the connection to the fuel supply system and exhaust pipe can be constructed simply and compact.
Conclusion: The delta combustion engine is a perfect combination of advantages between
Since the cylinder block is smaller on top ,the connection to the fuel supply system and exhaust pipe can be constructed simply and compact.
Conclusion: The delta combustion engine is a perfect combination of advantages between
4 strokes engine and 2 strokes engine, that also eliminates the disadvantages of the both types of engine. The delta engine will produce more power by less fuel consumption and reduction of unbalance effect. The 2 strokes engine half will run effciently without an additional support of scavenging blower. Nevertheless further development for boosting the intake pressure can be engineered by using supercharger or similar device and this will definitely improve the power.

4K3, 604 y86 8737 Delta engine cycle The first cycle of 4 strokes engine as well as 2 strokes engine starts normally with intake stroke, but for simplicity of the principle on combine engine (delta), let us consider the start / first cycle with power stroke.
Figure 1:
The compression is completed, both piston are at the top of compression stroke (TDC), intake and exhaust valves are closed. The air fuel mixture will be ignited by the spark plug, in diesel engine by the high air temperature, combustion occur in both compression chamber with a resultant expansion of gases and increase in pressure, forcing the pistons downwards.
Figure 2:
The 4 strokes piston with double speed moves to the bottom, while the 2 strokes piston with half speed of the 4 strokes piston's movement reaches respectively the half stroke of the corresponding piston, both are absorbing the pressure.
Figure 3:
When the 4 strokes piston reaches the bottom (BDC), the 2 strokes piston is exactly at it's half stroke, the power stroke is completed. The strong forces generated by power strokes will drive the 4 strokes piston to start with exhaust stroke, the 2 strokes piston is driven to complete the downwards movement.
Exhaust valve/ s at 2 strokes cylinder head is/ are about to begins to open.
Figure 4:
Exhaust stroke is generated by 4 strokes piston, with faster upwards movement of the 4 strokes piston, there is always pressure that remove the combustion product from the both chambers through fully opened exhaust valve/ s even the strokes piston still moving downwards slowly.
Figure 5:
The exhaust stroke continues until the 4 strokes piston reaches it's top position (TDC), there are still some exhaust products remain in the 2 stroke piston chamber, which have very low pressure and are able to be removed in the next cycle. Intake valve/ s is/ are about to open, while the exhaust valve/ s shall begin to close.
Figure 6:
The 3~d. Cycle begins for the 4 stroke piston, intake stroke. Intake valve/ s is/ are fully open. Low pressure in the 4 strokes chamber occurred by the downwards moving 4 strokes piston will bring the fresh air as well as the remaining exhaust product from the 2 strokes chamber. There are some ways to limit the flow of remaining exhaust product in to the lower pressured chamber:
J
Heru Santoso, Dipl.-Ing., 2683 Tempe Knoll Drive, North Vancouver, B.C., V7N
4K3, 604 986 8737 18'. Is to increase the air pressure during intake stroke by blowing or supercharging the intake air.
2"d. Is to design the channel in accordance with pneumatically one way valve.
3'd. Is to regulate the one way flow by additional valve. Etc.
With the above limitation the exhaust valve/ s can be opened for short time to remove the little remaining exhaust product during upwards movement of the 2 strokes piston. It is the common practise in the 2 stroke engine, that the remaining exhaust product including the heat energy will be diluted by the incoming fresh air, and this is in some extent improve the speed response of 2 strokes engine.
Figure 7:
The intake stroke in the 3'd. Cycle for the 4 strokes piston is completed, intake and exhaust valves are fully closed prior to this position. The 4'~'. Cycle for the 4 strokes piston begins, the 2"d. Cycle for the 2 strokes piston. The both piston are moving upwards and building pressure, a compression stroke. The gasoline engine using carburetor or fuel injector will have air -fuel mixture to be compressed up to certain ratio (9: I ), while in diesel engine the injection of diesel fuel will be conducted at later stage in the compression stroke with higher ratio(18:1).
Figure 8:
The compression strokes for both pistons continue, the air-fuel mixture in the strokes chamber is richer and will be pushed by higher movement of the 4 strokes piston in to the compression chamber of the 2 strokes piston. There will be a balance condition in the pressure, in the mixture and in the heat on the both chambers, that enhances the smooth and efficient condition for the next combustion stroke. All valves will not be opened until the power stroke is completed.
Conclusion:
The combination of 4 strokes engine half and 2 strokes engine half in delta engine enable to reduce the power consumption used to drive 2 another cycles, comparing with the conventional 4 strokes engine design for example in V-typed engine.
Response in speed is expected, since 2 stroke engine is producing power in every revolution and therefore generally better in responding the sudden demand of speed increase. Total performance will be absolutely improved, high performance and low fuel consumption.
The construction of delta engine requires additional crankshaft , which is not far different in weight, in Contrary, the centre of gravity becomes lower, that lead to better stability. Furthermore double crankshafts will affect better balance condition. Other advantages are, parts are still the same, the same maintenance, easy access ability, separate intake and exhaust manifolds, very compact design.
