Definitions
- the object of the invention is the construction of motorcycles, "quads”,
- the Japanese patent no. JP166997 from Hyundai Motor Co. Ltd. entitled “Two-Stroke Diesel Engine for motorcycle” aims to produce a two-stroke diesel engine for installation on a motorcycle by arranging a fuel injection pump in a special position with respect to to the engine
- the present invention utilizes the "common rail" electronic injection system with microprocessor management as is done in today's automobile diesel engines, which provides accelerations and performance similar to gasoline-powered motorcycles.
- SUBSTITUTE SHEET (RULE 26) • Lower traffic density, due to the reduction of the high space occupied on the road or large cities due to the majority use of the car. • High autonomy as a result of fuel consumption of approximately one third of that corresponding to a conventional gasoline engine.
- the application of the CDI-type system or high-pressure injection derivatives can be applied to any type of engine and combination of cylinder structure, to be mounted on a motorcycle or similar vehicle. Due to this system we have the great advantage that diesel engines substantially reduce their weight, while improving their performance.
- This invention generally encompasses any use of injection engines type CD1 and derivatives thereof applied to motorcycles, “quads”, “scooters” and motor tricycles as well as to electric generators, agricultural machinery, etc.
- the basic operation of the injection system of GDI type engines is as follows: In the low pressure system the fuel accumulates, is filtered and pumped to the high pressure system and cooled if necessary, This system is responsible for the production and accumulation of high pressure, intermediate accumulation and injection. An electric fuel pump pumps the fuel through a filter to the high pressure pump. Fuel is supplied to the "common rail” manifold, which is responsible for feeding the high pressure injectors. Through the return and cooling, the fuel returns to the tank. The pressure in the "common rail" is determined by the pressure sensor, and it transmits that information to the control unit.
- control unit knows the operation of the motor and the wishes of the driver, and is responsible for acting on the pressure regulating valve, applying variable current to regulate the pressure of the common rail and the opening time of the injectors according to the needs, Exhaust gases pass through the catalyst and come into contact with the platinum coating. Platinum accelerates the combustion process, but does not chemically modify it.
- the GDI engine can be mounted on the following chassis types; • motorcycle: steel tubular, double aluminum beam, aluminum tubular, square steel tubular, double bearing beam and double cradle tubular; • conventional "scooter”; • conventional "quad”; • that the chassis is the engine itself
- the invention is to apply a diesel engine with a "common rail" system regardless of the type of construction or arrangement of cylinders, being able to be of many types, such as a single-cylinder, an inline bicyclic, an in-line three-cylinder such as SMART, a in-line four-cylinder, a "V" twin-cylinder, a “V” four-cylinder, a “boxer” two-cylinder and others, being able to add to the different combinations cylinder heads with 2 camshafts and 4 valves per piston instead of a shaft cams and 2 valves per piston as the SMART carries.
- This invention highlights the application of the CDI type system or injection derivatives to any type of 4-stroke engine and combination of cylinder structure to be mounted on a motorcycle or "quad". Due to this system we find that in the diesel engines equipped with this CDI type system or injection derivatives its final weight is substantially reduced and its performance is improved.
- the invention comprises three possibilities; a) application of a commercial CDI type diesel engine, b) application of a commercial CDI type diesel engine, but with a block adapted to the needs of the application and c) conversion to GDI type diesel engine technology of a motorcycle or vehicle series engine of this type, always being the application of diesel engines to motorcycles and similar vehicles.
- the clutch system is replaced by one of multi-discs bathed in oil and operated by a bolt which in turn is pulled by a conventional motorcycle system cable.
- a cylinder head with 2 camshafts and 4 valves per piston can be equipped on the engines.
- the second possibility b), that is to say the application of a commercial GDI type diesel engine, but with a block adapted to the needs of the application, consists in using not exactly the engine but its parts that do not require adaptation together with a manufactured engine block in 2 pieces with suitable housings for the new change and with the corresponding adaptations of the different relocated elements.

- the third possibility c) consists of another manufacturing formula much cheaper and wider than the previous ones, which is the use of a conventional motorcycle engine, usually the vehicle's own engine, but adapting it to the "common rail" system by means of the relevant modifications, applicable to any type of motorcycle engine, be it single-cylinder, two-cylinder, etc. Starting from the engine with change, and in general a modification of the cylinder head is required, even with two overhead camshafts, to which all components of the common rail injection and turbo system are adapted with some ease.
- the operations to be carried out are: 1) Modification of the materials of the driving parts and bushing, cylinder head, etc. for having to endure more violent combustion so as not to lose reliability. 2) Creation of camshafts in accordance with the engine to be developed. 3) Adaptation of the compression suitable for the small turbo that is coupled and creation of a new exhaust manifold with these characteristics. 4) Creation in the motor cover of anchors to support the "rait", which will be screwed to it. 5) Carrying out some machining in the cylinder head to hold the high pressure pump and the vacuum pump with their corresponding holes to be able to receive movement of the camshafts. Said movement drag is communicated by a simple system such as the coupling of the water pump mentioned above.
- the intake camshaft is responsible for transmitting the movement to the discharge pump, and the exhaust camshaft to the vacuum pump, a vacuum necessary to regulate the turbo blow pressure, by means of a solenoid valve governed by the module. 6) Creation of an optimal intake manifold for the new engine. 7) Modification of the intake ducts for the new system,
- a vacuum pump is activated, which is used to actuate the lung, but this step is governed by an electric valve that is responsible for giving way or removing it under vacuum by means of a electrical signal sent by the CPU module, operating more or less the lung and this is responsible for opening or closing the passage of exhaust gases, which transmit more or less movement to the turbo exhaust blades and these to be in solidarity with
- the intake blades are responsible for giving air pressure to the engine according to its needs. That pressure in the intake manifold is responsible for measuring the pressure sensor and it sends that information to the CPU module, so that it can be evaluated according to the needs and the injection cartography it has, also influencing the injection time.

- the water pump is relocated next to the oil pump, which is the one that sends the movement to the water pump, through mechanized lugs that rotate in solidarity with the water pumps, the left one, and the oil pumps , the right. Bearing in mind that new coolant lines must be created, considering all the modifications at once.
- SUBSTITUTE SHEET (RULE 26) 11) Optionally it can be equipped in engines (50) A cylinder head with 2 camshafts and 4 valves per piston.
- a second preferred embodiment of the present invention consists in the application of a SMART CDI diesel engine to the same chassis types (11-15, 26-28) of the First Preferred Embodiment, but with a block adapted to the needs of the application , that is to say, the engine is not used exactly but its parts except the block, and the new engine block is manufactured in 2 pieces with suitable housings for the new change and with the corresponding adaptations of the different relocated elements.
