Abstract
The utility model relates to a direct injection 4100 energy saving type diesel engine. Under the condition that the cylinder head, the connecting bolt and the coordinate dimension of a 495T type diesel engine with a swirl chamber are not changed, a cylinder bore diameter uses 1 as reference and a combustion system is newly designed and configured according to a relative scale. Particularly, after the head helix of a helical intake passage is established with a new trace according to a mathematical model, the combustion system is optimized to reach the technical design indexes of high rotating speed 3200 rpm.), large power (58.8 kW), low rate of oil consumption (< =217.6 g/kW. h), light night weight and high coefficient of intensification (85.9CmPe. Therefore, the utility model is suitable for being used as lightweight automotive power.
Description
The utility model 4100 energy-saving diesel engines belong to straight spray firing chamber diesel engine for automobile, are particularly suitable for as two tonnes of automobile-used power.
Present domestic diesel engine with direct injection at the same level, its power performance, economic indicator are all undesirable, for example: LR4100 diesel engine and 4102AZ diesel engine that domestic major vendor produces, its rotating speed low (rotating speed is all below the 2800r/min), power is little, fuelling rate is high (all more than 224g/km.n), coefficient of intensification is low and clean quality is bigger.
The utility model is exactly in order further to improve the power character and the Economy of diesel engine with direct injection, particularly in order to improve the technical-economic index of two tonnes of derv fuel mechanomotive forces.Thereby new design and configuration on its combustion system, have been done.
The utility model direct spray type 4100 diesel engine mainly comprise and are opened in spiral inlet duct (1) on the cylinder head, an oil nozzle (3) and one by one and are arranged at the combustion system that the firing chamber (5) at piston (4) top is formed.
The head spiral of spiral inlet duct is by mathematic(al) mode P=a0,2 兀 a=OA tracks form, and the position of the relative cylinder of spiral inlet duct, are under the condition when setting cylinder bore D=1, intake valve diameter d=0.4～0.5 of said spiral inlet duct, intake valve and cylinder wall are apart from G
1=0.02, intake valve departs from cylinder axis G
2=0.05, intake valve center to angle=78 of cylinder axis line and cylinder cross central line °～79 °
When setting D=1 with cylinder bore, oil nozzle center and cylinder axis lateral run-out J
1=0.12, vertically depart from J
2=0.025, angle=23 of oil nozzle axis and cylinder vertical center line ° on the cylinder head～24 °
When cylinder bore was set D=1, directly spraying firing chamber misalignment cylinder axis was horizontal P
1=0.06, longitudinal P
2=0.01, its firing chamber diameter D
2=0.55～0.60, make that combustion-chamber depth is H, then firing chamber diameter and the ratio of its degree of depth are with D
2/ H=3.32 is best.
The utility model 4100 energy-saving diesel engines are mainly after direct injection combustion system is further realized new optimal design, configuration, make these facility that good and economic and power character be arranged, for example: the 4 cylinder machines that when cylinder diameter are 100 millimeters, its peak output/(rotating speed) can reach 58.8km/3200r/min, Maximum Torque/(rotating speed) 200.9/2200r/min, with two tonnes of automobile accessories horsepower/tons is 20PS=T, and moment of torsion/ton reaches the foreign level scope for 5.1kg.m/l.Its minimum consumption rate of fired oil≤2176g/km.h, specific oil consumption≤1g/km.h, environmental index: exhaust smoke, the maximum smoke intensity of external characteristics≤3.6 ripples are permitted.Therefore the present invention is specially adapted to as 2～3 tonnes of Light-duty Vehicle mating power.

Embodiment:
With cylinder diameter is that 100 millimeters four-cylinder 4100QB is an example: the head spiral of its spiral inlet duct is by mathematic(al) mode P=a0,2 兀 a=OA tracks are set up, and the position of the relative cylinder of spiral inlet duct, then carry out Design Orientation under the condition when setting cylinder bore D=1, be intake valve diameter d=0.45 of this spiral inlet duct, intake valve and cylinder wall distance are G
1=0.02, intake valve departs from cylinder axis G
2=0.05, intake valve center to the angle of cylinder axis line and cylinder cross central line gets=and 78 ° 41 ' for best; Oil nozzle center and cylinder axis lateral run-out J
1=0.12, vertically depart from J
2=0.025, on the cylinder head angle of oil nozzle axis and cylinder vertical center line get=23 ° for best; Straight spray firing chamber misalignment cylinder axis is horizontal P
1=0.06, longitudinal P
2=0.01, its firing chamber diameter is got D
2=0.565, and get combustion-chamber depth H=0.17, the ratio D of firing chamber diameter and its degree of depth then
2/ H=3.32 is an optimum value.
