The coach diesel engine is an internal combustion engine that uses diesel fuel. Diesel engines are compression-ignition engines, which are often referred to as the diesel engine in the name of the main inventor, Diesel. When the diesel engine is in operation, the air sucked into the cylinder of the diesel engine is subjected to a relatively high degree of compression due to the movement of the piston and reaches a high temperature of 500 to 700°C. Then, the fuel is sprayed into the high-temperature air in the form of mist, and mixed with the high-temperature air to form a combustible mixture, which automatically burns on fire. The energy released in the combustion acts on the top surface of the piston, pushing the piston and converting it into rotating mechanical work through the connecting rod and the crankshaft. Compression Garbage Truck In the daily use of the diesel engine in the coach, some common faults directly affect the service life and production efficiency of the diesel engine. So it is very important to understand the failure of the diesel engine. Below we introduce common diesel engine failures and analysis of the causes of failures.
The coach engine's diesel engine power drops or the engine emits black smoke:
1. The air filter is dirty (clean or replace)
2. Leakage at the connection between the outlet of the diesel compressor and the exhaust pipe (tighten the clamps or fasteners)
3. Leakage at the connection between the turbine inlet and the exhaust pipe (replacement of gaskets, tightening of fasteners)
4, the engine intake pipe leakage (replacement gasket, tighten the fasteners)
5, diesel exhaust pipe rupture or gasket damage (replace the exhaust pipe or gasket, tighten the fasteners)
6, Diesel compressor impeller contamination (cleaning)
7, diesel engine pressurized gas damage (repair or replace)
8, diesel fuel system failure.
Diesel engine compressor seal ring leakage
1, diesel engine air filter is too dirty (clean or replace)
2. Inspiratory air duct obstruction or contamination of diesel engine compressor (removal of dirt)
3, supercharger return pipe is not smooth (clean or replace)
4. Pressurized air middle shell lubricant coking and sludge (clean or replace turbocharger)
5, engine piston ring or liner wear
6, diesel engine pressurized gas damage (repair or replace)
Coach diesel engine turbine seal ring leak
1, the supercharger return pipe is not smooth (clean or replace)
2. Lubricator coke and sludge in the middle shell of the supercharger (clean or replace the supercharger)
3, engine piston ring or liner wear (repair or replace)
4, turbocharger damage (repair or replace turbocharger)
The abnormal sound of the diesel engine of the coach
1. Compressor Suction Blocking Leads to Compressor Surge
2. Compressor impeller fouling, resulting in compressor surge
3, the air intake system leaks abnormal sound
4ã€Abnormal noise caused by air leakage in outlet system
5, the rotor touch the shell
6, diesel turbocharger damage (repair or replace turbocharger)
Train engine's diesel engine oil consumption rises
1, the supercharger return pipeline is not smooth (remove dirt)
2. Damage to the turbine seal ring (send turbocharger repair station repair)
3, diesel compressor seal ring damage (send booster repair station repair)
4. Accumulation of a large amount of oil sludge in the middle shell of the supercharger (repair of supercharger repair station)
5, turbocharger damage (repair or replace turbocharger)
6, diesel engine oil brand does not meet the requirements (replacement of suitable oil)
