Delong cab injector seal due to poor fuel leakage First, look closely at the top of the melt has Delong cab piston. The cylinder has been strained cylinder, piston rings and piston ring grooves also stick together. Obtained by observing the cab company, the cylinder and piston and piston ring grooves strain adhesion is due to melting caused by the piston crown. Therefore, the friction heat exclude improper assembly by the mechanical part or discomfort caused by the choice of materials and lead to the possibility of the melting of the piston top Delong cab, but also ruled out by examining the factors that caused the engine temperature is too high and melt the top. And to provide a detailed understanding of parts manufacturers, the exclusion of parts itself. After the adoption of a comprehensive analysis, judgment, we conclude that the failure occurs in Delong cab vehicle fuel system on the injector. Since Iveco vehicle fitted with a diesel engine, the injector working conditions directly affect the operating conditions of the engine. Thus, not only requires a certain pressure injector can spray into the cylinder diesel, but also requires its accuracy when injection is being evenly distributed, good atomization. Delong Cab circuit fault considerations usually some customers to buy Delong cab circuit failure will reflect the experience will know what to do, Linyi cab, do not know how to do, but because they do not know what to pay attention to, the original cab, I am not start. The following is a summary of your Delong cab, of course, other heavy-duty truck cab for the same experience. Common circuit failure are: open circuit, short circuit, damaging electrical equipment and so on. Spontaneous combustion accidents in which the circuit fire occupy a large proportion of spontaneous event. Among the aging circuit and excessive load are reasons cab circuit. When using Delong cab must pay attention to the following questions: 1, due to high temperature operation of the engine ignition coil, HOWO cab shell, easy to soften the high-voltage ignition wire insulation, and aging, crack on ignition high-voltage insulation breakdown easily produce high-voltage leakage, short circuit resulting in spontaneous combustion. 2, Delong cab has more and more electronic control technology, intelligent application also makes a substantial increase in cab electronic respective power. However, due to limited on Delong cab circuit system load space, microcomputer, electronic components, various sensors circuit systems are likely to cause damage, because a large number for the cab increase the variety of additional electronic equipment, may also increase the burden on the circuit, thereby Fire caused by spontaneous combustion. 3, Delong cab electronic circuit system will lead to the loss of old car more fuel, throttle flow, ignition efficiency is not high, the shift poor, lack of motivation and so on. These indeed affect the whole body of small problems related to the vehicle power supply related, too easy to become unable to solve the problem.
