Performance of insufficient compression pressure in Perkins diesel cylinders.
Perkins diesel engines, as a common engine type, are widely used in various machinery and vehicles. However, sometimes there is a shortage of cylinder compression pressure, which can negatively affect the performance and life of the engine. This article will introduce the performance of insufficient compression pressure of Perkins diesel engine cylinder in detail, and help users find and solve problems in time.
First, it is difficult to start.
When the cylinder compression pressure is insufficient, the engine may become difficult to start. When trying to start the engine, you may hear the starter turning, but the engine does not start properly. This is because the gas pressure in the cylinder is insufficient, which causes the fuel to not burn properly, making it impossible for the engine to start.
Second, the power decreases.
When the cylinder compression pressure is insufficient, the power of the engine may be affected. Even if the engine is able to start, during operation, a significant drop in power may be felt, manifested as a muffled engine sound, slow acceleration, reduced load capacity, etc. This is because the gas pressure in the cylinder is insufficient, resulting in insufficient fuel combustion, which affects the power output of the engine.
3. Black smoke.
When the cylinder compression pressure is insufficient, black smoke may be emitted from the engine during operation. This is because the gas pressure in the cylinder is insufficient, resulting in insufficient fuel combustion, which produces a large amount of unburned carbon particles, which forms black smoke. This situation not only negatively affects the performance of the engine, but also causes pollution to the environment.
Fourth, the water temperature is abnormal.
When the cylinder compression pressure is insufficient, the water temperature of the engine may be affected. During operation, the water temperature may rise or fall abnormally. This is because the gas pressure inside the cylinder is insufficient, resulting in insufficient fuel combustion, which generates a lot of heat, which increases the water temperature. At the same time, due to the insufficient pressure of the gas in the cylinder, the heat dissipation effect of the engine may be affected, which will reduce the water temperature.
Fifth, fuel consumption increases.
When the cylinder compression pressure is insufficient, the fuel consumption of the engine may increase. This is because the gas pressure inside the cylinder is insufficient, resulting in insufficient fuel combustion, which increases fuel consumption. In addition, due to the decrease in engine power, in order to maintain normal operation, the amount of fuel** needs to be increased, which leads to a further increase in fuel consumption.
In summary, the manifestations of insufficient compression pressure in Perkins diesel engine cylinders include difficulty in starting, power drop, black smoke, abnormal water temperature, and increased fuel consumption. When these situations occur, the problem of insufficient cylinder compression pressure should be checked and eliminated in time to avoid negative impact on the performance and life of the engine. At the same time, in order to prevent the problem of insufficient cylinder compression pressure, the engine should be regularly maintained and maintained to maintain the normal working condition of the cylinder.
