Usually, the Bitzer 4TC piston kit we use can be replaced for life. As long as the engine works normally, the idle speed is stable, the power output and fuel consumption do not change much, and the exhaust gas does not emit blue smoke, there is no need to replace the piston.

The Bitzer 4TC piston kit is the reciprocating part in the engine block. The basic structure of the piston can be divided into top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the type of combustion chamber selected. Gasoline engines mostly use flat-top pistons, which have the advantage of small heat-absorbing area. There are often various pits on the top of the diesel engine piston, and their specific shape, location and size must be adapted to the requirements of the diesel engine's mixture formation and combustion.

Signs to replace Bitzer 4TC piston kit:

1. When the engine is overhauled, if it needs to be replaced, it is the principle of replacing the original parts. According to the old standard, when the vehicle travels 100,000km, it needs to be replaced, but the design of new cars can sometimes even run to 20,000KM without replacement, so The "phenomenon" is not uncommon, and the actual inspection is the standard.

2. When it is felt or found that the power performance of the engine is significantly reduced, and the edge of the cylinder block is too worn after inspection, or the end clearance of the Bitzer 4TC piston kit exceeds the standard. When the consumption of fuel and lubricating oil increases sharply, and the spark plug is prone to carbon deposition.

3. Reasons for driving, maintenance, lubrication system, etc. cause the Bitzer 4TC piston kit to break.
