Hybrid Synergy Drive 2.5L Atkinson cycle hybrid engine

Product features:

The core is to achieve ultra-high thermal efficiency(>41%).The Atkinson cycle achieves an expansion ratio greater than the compression ratio by delaying the closing of the intake valve,thereby improving thermal efficiency.The electric variable valve timing system achieves stepless adjustment of valve timing.The cooling exhaust gas recirculation system effectively suppresses detonation and reduces pumping losses under moderate loads.The engine works most of the time in the high-efficiency range,seamlessly coupled with two motors through a planetary gear set(power distribution device),achieving various driving modes such as pure electric and hybrid.The optimized cooling and lubrication system reduces mechanical friction losses.

Product specifications：

Cylinder diameter x stroke:90.0mm x 98.0mm;Compression ratio:14.0:1(effective expansion ratio);Highest thermal efficiency point:about 41%;Emission standard:ultra-low emissions(SULEV);Oil capacity:4.4L;Recommended oil:SAE 0W-16 ultra-low viscosity oil;Engine control system:integration of ECU and hybrid system controller;Net weight:approximately 110kg(excluding motor).Adopting high-energy ignition coils,low tension piston rings,and electric water pumps,traditional starters and generators are eliminated.

Product application:

specifically designed for strong hybrid vehicles,including hybrid sedans,SUVs,and MPVs.As the"generator"of the hybrid system and the"main driving source"during high-speed cruising,it works in conjunction with the battery pack and driving motor to achieve low fuel consumption and worry free long-distance driving on urban road conditions.Widely used in high-frequency usage scenarios such as urban taxis and ride hailing services,greatly reducing operating costs.Its smooth start stop and quiet operation characteristics also enhance the luxury of the vehicle.The technology platform can be extended for plug-in hybrid vehicles.
