What is cylinder deactivation?

Cylinder deactivation technology is the use of mature components.，Under specific working conditions，Causes the engine valves for the selected cylinders to no longer operate，Achieve better engine fuel economy。Higher exhaust temperature for cylinders that are still operating，After-treatment system can be kept at high temperature at low load and start-up，Reduce the emission of nitrogen oxides。

Read the working principle.，Do you think that the cylinder deactivation technology is as simple as shutting down the surplus cylinders in operation?？Then you will underestimate this new technology.！When it is applied to the engine，Gain more than you expect！

Performance advantages，At a glance

Reduce pumping loss and friction work，Improve fuel economy

Engine and aftertreatment systemPreheat faster

Optimize combustion，Reduce fuel consumption of ignition cylinder

Under low load condition，Keep aftertreatment system at high temperature，And that emission performance is improve

SlidingReduces cooling losses in aftertreatment

Hydraulic drive mechanism integrated in the push rod or valve bridge，And that system integration is high

Interlinked with high power braking technologyModular design，Efficient module upgrade

Fuel consumption improvement with three cylinders deactivated(%) 

Increase in exhaust temperature after three cylinders are deactivated(℃)
