What is the horsepower of the Changchai 4L88 engine?

[AxelLee]

Changchai 4L88 engine is 88 horsepower. The following is an introduction to the Changchai 4L88: 4L88 Series: The Changchai 4L88 diesel engine is an upgraded model based on the 4L68 with added turbocharging, so its base power is 50KW/3200 rpm, equivalent to 68 horsepower. The power of the Changchai 4L88 is 65KW/3200 rpm, equivalent to 88 horsepower. This model is designed for vehicle use. There is also a specialized version of the Changchai 4L88 for harvesters, with a power of 48KW/2400 rpm. Related Technology: This diesel engine can also be equipped with intercooling technology and upgraded to the 4L98 model, increasing the power to 72KW/3200 rpm.

I specialize in agricultural machinery maintenance and have disassembled many Changchai 4L88 engines. This four-cylinder diesel engine has a base model output of around 55 horsepower, but the exact power depends on the suffix designation. For example, the 4L88-110 model has a net power of 40 kW (approximately 55 hp), the 4L88-120 model about 42 kW (57 hp), and the high-pressure turbo version can reach 46 kW (62 hp). Actual horsepower can be affected by altitude, fuel quality, and maintenance conditions. A machine operated by someone in Northeast China at -20°C might lose 3-4 hp. It pairs well with small four-wheel tractors for hauling two tons of cargo with ease, but it's recommended to check the injector pressure every 500 hours.

Last year when purchasing tractors for the cooperative, I researched this model. The Changchai 4L88 series has a power range between 55-62 horsepower, equivalent to 40.5 to 45.6 kilowatts. Note that the 12-hour power rating marked on the engine nameplate is the effective value—don't be misled by the 1-hour peak power. When matching with a 1.8-meter rotary tiller, it's recommended to maintain the working speed at 2200 RPM for optimal torque reserve. Remember, opting for the high-altitude turbocharging kit can extract an additional 5% power in regions like Yunnan and Guizhou.

I discussed with the factory technician at the agricultural machinery exhibition. The factory test data for the 4L88 new engine shows a rated power of 58 horsepower (42.6 kW), with a maximum torque of 216 Nm at 1600 rpm. However, after three years of actual use, power may decrease by more than 10% due to belt slippage and air filter clogging. If paired with a 65 cm deep tillage rotary cultivator, it is recommended to use the low-speed gear of the transmission. Their technical manual mentions that valve clearance should be adjusted every 100 working hours, which is crucial for maintaining horsepower.
