OEM No/Model: YC4Y
Model introduction
4 AVL y20 diesel engine is the engine of international famous design company design, advanced by AVL, yuchai joint development of a new high-speed direct injection diesel engine. Product positioning: the domestic first-class, international leading, satisfy the above 5 and emissions regulations. Power 55 kw/L, litres torque 165 n. m/L, power performance index has reached the international advanced level.
Model features
1. fuel-efficient
Advanced design idea: bias in the plane of the crankshaft and cylinder hole center design, and the performance of the reasonable design and combustion development, make the engine high efficiency and 2. energy saving.
Using system: during 1600-1800 bar high pressure up to 5 times the injection capacity, flexible control, effectively reduce the fuel consumption, emissions, noise, in line with the euro 5 emissions.
Variable nozzle turbocharger, inlet variable eddy: increase engine power and dynamic response, increase the torque at low speed; The vehicle speed fast, and reduce the fuel consumption and emissions.
3. Low emission
Four valve, double overhead camshaft: intake enough, oil steam mixing, improve power and reduce fuel consumption and emissions.
With a bypass valve EGR cooler: driven by dc motor, responsiveness faster; Stronger resistance to carbon deposition ability; And avoid sticking effectively, reduce the emissions.
4. Highly reliable
Reliable and durable, passed the European machinery development program of strict examination, the service life of more than 300000 kilometers.
Dry deep skirt + trapezoid framework base cylinder body, composite sandwich pan: the whole strength and the rigidity is excellent, effectively reduce the vibration noise, reasonable structure equilibrium.
5. Low noise
Chain transmission, hydraulic lifter: quiet and durable, the chain lifetime maintenance free.
Reasonable professional design makes the engine cylinder block, base quiet and comfortable, good quality sound.
Dual mass flywheel (optional) : shut vibration, good comfort, provide vehicles is an advanced configuration of diesel passenger cars to ensure comfort.
