The tappet cover, also known as the valve cover, is a component in internal combustion engines that houses the tappets, or valve lifters, and protects the upper part of the engine, including the camshaft and valves. It is usually made of metal or durable plastic and is sealed to prevent oil leakage. The tappet cover also helps to keep contaminants out of the engine and maintains proper oil circulation. Its design often includes ventilation features to manage engine pressure and reduce oil mist.

Gas turbines are a type of Internal Combustion engine, however; Assuming that you want to know the difference between a recpirocating piston engine and a gas turbine engine, the simple answer is that ICE's (Internal combustion engines) create work by moving a crank that is connected to a piston. An explosion in the piston chamber pushes a piston (or series of pistons) attached to a crankshaft, which turns the shaft. The gas turbine works by turning a shaft connected to a turbine. The turbine is powered by a compressed feul-air mixture. A stream of gas is compressed with air and forced through a chamber containing the turbine. The turbine turns the shaft as a result of complex mechanics that control the movement and flow of the compressed fuel-air mixture. The basic mechanical difference: A reciprocating piston engine uses a linear "back and forth" motion to turn a shaft, and the gas turbine engines relies on a constant circular motion to turn a shaft.
Internal combustion engines produce a lot of waste heat. So much so that if this excess heat is not removed the engine will weld itself into a immobile blob.

IC & EC engines are heat engines and they convert heat into work. Example of an IC engine is a petrol engine and example of an EC engine is Steam Engine. The main differences between them are listed below: 1) Combustion: The main difference is where the combustion takes places. In IC engines fuel combustion takes place inside the cylinder, whereas in EC engines it takes place outside the engine cylinder. 2) The temperature and pressure in an IC engines is much higher than those of EC engines. 3) IC engines are made of materials that are better resistant to heat and pressure than in EC engines. 4) In IC engines the piston is directly connected to connecting rod, whereas in an EC engine there is a stuffing box. 5) Efficiency is higher for IC engines. 6) Boilers are required for EC engines to store water, which is to be converted to steam. But IC engines require only a much smaller tank to store fuel. 7) EC engines, unlike IC engines cannot be started or stopped quickly, because it takes time to initiate boiling of water and generate steam. 8) IC engines are lighter than EC engines. 9) IC engines are cheaper compared to EC engines.

The tappet cover(s) is located on the cylinder head, it is usually round in shape on a motorcycle. On a car, it is more commonly known as a "valve cover" and is the rectangular shaped cover & all the four corners has chamfered shape
Automobile engines are ic (internal combustion).
what is the tappet clearance for PD_6 Nissan diesel engines thus engine is 6 cylinder in line thanks jani king
Its a tappet adjustment that to be done for diesel engines to overcome the noisy sound from the engine which get loose by continueously uses of the vehicle .
Diameter of the piston head.
This is the ratio between the total volume to the clearance volume in IC engines
