OUJIAXIN Motor 1.8L LFB479Q Engine For Lifan X60 620 720 820 LFB479Q Engine Assembly

Description

Multi-point EFI 1.8L naturally aspirated gasoline engine, the engine management system is jointly developed with Delphi, and the ECU adopts Delphi’s latest system template characterized by torque, which is advanced in technology; inline four-cylinder, roof-shaped combustion chamber, displacement 1.8L, double overhead camshaft technology, engine operation is more reliable; timing chain transmission ensures more accurate valve timing, 16-valve intake and exhaust are more adequate; Quantitative design concept, a large number of engineering plastics and light aluminum alloys are used as raw materials for component development; catalysts with high emission purification rate and superior heating characteristics are used, and the emissions meet the National IV standard, and can reach the National V emission standard through optimization and matching.

At the same time, the lightweight engine, low-friction piston and piston ring, low-inertia moving parts, stainless steel exhaust manifold and front-stage catalytic converter are tightly coupled.

Among them, the intake VVT technology is a device that controls the timing phase of the intake valve.

At idle speed, the intake phase is minimized to reduce idle speed and improve fuel economy; at medium, low load/medium and low speed, the intake phase is slightly advanced to reduce intake vacuum and pump air loss; at high load, medium and low speed, the intake phase is advanced to improve charging efficiency and torque at medium speeds, and at the same time, further reduce intake vacuum and reduce pump air loss.

Thereby improving the power performance and fuel economy of the engine in the higher speed range, and reducing exhaust emissions.

Technical innovation point: Intake variable valve timing VVT design.

The lightweight design of the engine has been carried out.

Low friction piston and piston ring design.

Low inertia moving parts design.

The stainless steel exhaust manifold is tightly coupled with the pre-catalyst.
