How big is the cylinder diameter of Changchai 4乚88 engine

1. Maximum output power: 65KW. Maximum horsepower: 88 horsepower.

2. Changchai 4L88 diesel engine is an upgraded model after supercharging on the basis of 4L68, so its basic power is 50KW/3200 rpm, which is equivalent to 68 horsepower.

3. It refers to 4 cylinders with a cylinder diameter of 85 mm, but the cylinder diameter is the same and the connecting rod stroke is different, the displacement is different. With the same cylinder diameter, the longer the stroke, the larger the displacement.

4. It is a diversified large enterprise group. Changchai's main product is to produce single-cylinder and multi-cylinder small and medium-power diesel engines. The main product of Tin Chai is 6DL, which is the research and development, production and sales of diesel engines. The main product of Chaochai is 4102. In the past, it mainly produced agricultural machinery accessories and agricultural machinery testing equipment. Later, it operated agricultural diesel engines.

Changchai 4l88 engine oil usage

How many liters of engine oil should be added at a time depends on the type of engine. Generally, small-displacement cars need to add 2 to 6 liters of oil for each maintenance, and about 5 liters for large displacement.

It will take about 5~0 liters to change the oil of the car. How many liters of oil to add at a time depends on the type of engine. Generally, small-discharge vehicles need 2-6 liters of oil, and large-dismission vehicles need about 5 liters. The fuel should not be too little, and at the same time, it should not be too full.

liter. According to the information of Auto Home, Changchai's 125 horsepower four-cylinder diesel engine is full of power and stable performance, and needs to add 8 liters of oil. Changchai Co., Ltd. is a national industrial enterprise with a 100-year history. It is one of the earliest professional manufacturers of internal combustion engines in China, and the first listed company in the national agricultural machinery industry and Changzhou.

~6 liters, about 5 liters is needed if the displacement is large. Take myself as an example. I only need 4 liters of oil for a 4T model. I usually use Jinjixing of 4L Great Wall lubricant. The clerk usually doesn't take the initiative to tell me the rest, but I will ask every time to take back the remaining 0.6L and use up the defect.

The main reason is that the amount of oil used in cars is different. Some car oil can only load 5 liters, and some can load more than 4 liters. Different models have different oil usage. There can't be less oil. Less oil will cause the x0dx0ax0dx0a engine to overheat and damage the service life of the engine.

Changchai 4L88 has several power

1. Horsepower. The Changchai 4l88 engine has 88 horsepower.The 4L88 engine is a brand-new product jointly created by Changchai and Great Wall, with a displacement of 8 liters and a power of 65 kilowatts. The fuel consumption rate of the engine is greatly reduced, and the fuel consumption per 100 kilometers is less than 6 liters.

2. Engine. The 498 engine has 30 or 40 horsepower more than Changchai 4188. 498 is one of the most mature engines in light truck applications, with high horsepower, fast acceleration and fuel-saving. The 498 engine is more advanced in technology. The 498 engine is more practical than the 4188 engine in terms of fuel consumption, emissions and durability, so the 498 engine is better.

3. The price and horsepower are different. The price is different. The price of Changchai 4l88 is 4,200 yuan, while the price of Changchai 4g33 is 6,800 yuan, which is not cost-effective. The Horsepower Is Different. The horse of Changchai 4l88With large force, there are more items that can be driven, while the horsepower of Changchai 4g33 is relatively small, and there are fewer items to drive.

4. Changchai's current single-cylinder diesel engines mainly include S, ZS, R, F, L, D, SQD and H eight series of products, and multi-cylinder diesel engines mainly include 75-80, 85-90, 4L and 102 series of products, with a power range of 7~72 kilowatts, a total of 1000 Multiple varieties.

What's the problem with the acceleration and shutdown of the harvester Changchai 4l88 engine

Fault phenomenon: the engine at a medium or above speed It works normally during operation. When the rotational speed is idle or close to idle, the phenomenon of unstable idle speed or even shutdown occurs, which is a bad idle speed failure. (2) Cause of failure: Poor idle speed is usually caused by the intake system and fuel injection control system. In some cases, poor idle speed will also be caused by engine mechanical failure.

Reasons for the oil supply system: This may be caused by the blockage of the low-pressure oil pipeline, the loose oil leakage of the pipeline, the air in the high-pressure oil pipe, the technical condition of the fuel injector or the incorrect timing angle of the fuel injection.These conditions may affect the normal oil supply of the diesel engine, resulting in the problem of not adding oil or turning off the engine.

The high-voltage coil of the distributor has shortcomings - if the spark plug is intact and the engine is still extinguished, it may be caused by dents at the power outage point or excessive erosion. The power-off point with too large dents indicates that the distributor has lost its utility.

Is the unstable throttle of Changchai 4l88 engine related to the new crankshaft replacement?

1. The throttle valve is faulty. The above two problems will cause engine shaking and unstable speed. Carbon accumulation will cause insufficient combustion of gasoline, causing the engine to shake.

2. First of all, change the oil of the diesel pump. If it doesn't work well, it means that the "advancer" is broken. Just change one.If the crankshaft is not replaced, the impact of the connecting rod piston is generally small.

3. There is nothing to do with the crankshaft without oil. It may be that the mixture is too thin or there is no preheating after starting, which may lead to no refueling, or it may be an engine problem. First, check whether there is too much oil. If it is an electric injection vehicle, it is recommended to clean the throttle valve. If it is a linear throttle car, check whether the oil line is rusty.

4. Excessive wear or breakage of the four-stroke engine, as well as too much oil in the crankcase, will cause the oil to enter the combustion chamber and cause excessive oil in the mixed gas. If the oil seal of the crankshaft of the two-stroke engine is broken, it will also cause the oil in the transmission to enter the crankcase and enter the combustion chamber with the mixed gas.

5. The overhaul of automobile engines mainly includes the replacement of valves, pistons, cylinder liners, or boring cylinders, grinding shafts, etc.According to the standard of general 4S stores, 4 accessories need to be replaced, that is, piston, piston ring, valve, valve oil seal, valve duct, crankshaft tile, connecting rod tile, timing belt, tensioner wheel.

6. Not counted. The connecting rod tile crankshaft is a little tight due to the low running-in degree caused by the new replacement. After driving for a period of time, the running-in degree will return to normal. It is a normal phenomenon, not a disease. An engine is a machine that can convert other forms of energy into mechanical energy.
