Is Changan CS75 Blue Whale Edition OK?

High-pressure direct injection technology is leading the industry, and the engine will only allow fuel to be injected twice at most. However, this engine of the new CS75 can realize up to five fuel injections in one stroke. Throughout the world, among the models that have been mass-produced, it has the most RF spraying times.

The scavenging function is accurate and efficient, the linear oxygen sensor accurately calculates the air-fuel ratio, and with the fine bench calibration and DVVT technology, the strong scavenging function is realized, so that the fuel injection is closed-loop controlled under all working conditions, the low torque is increased by more than 20%, and the maximum torque speed is reduced to 1450rpm.

Disadvantages of blue whale engine:

The common problem of blue whale engine is that when the engine is in the high speed range, the engine noise can easily enter the car.

The maximum power 1 15kW and peak torque of 225 N m. The fuel economy of the backward multi-point injection system is much worse. In addition, when the speed is increased, the gearbox downshifts slowly and the delay is serious.

Matters needing attention in using Blue Whale engine:

When the engine is running, be sure to check the values of oil pressure gauge and coolant thermometer. If the values of oil pressure and water temperature are greatly different from the usual values, please stop immediately for inspection or contact Dongfeng Cummins service station.

If the engine is overheated during driving, the power output can be reduced by releasing the accelerator pedal, shifting the gearbox to a low gear or both until the engine temperature returns to the normal working range. If the engine temperature cannot return to normal, please shut down the engine for inspection or contact Dongfeng Cummins service station.
