Types of Engine Valve Mechanisms:
1, The valves are operated by cams mounted on a camshaft. The camshaft gets motion from the crankshaft. As the camshaft turns, the cam operates the valve.
2, According to the loafter market dieselion of the valves, the valve mechanism is of two types:
Valve mechanism for operating the valve in engine block (straight poppet valve).
Valve mechanism for operating the valve in the cylinder head (overhead poppet valve).
3, Valve-Tappet Clearance
A slight clearance is kept between the valve tappet and the valve stem in the case of the straight poppet valve, and between the rocker arm and valve stem in the case of the overhead poppet valve. This is known as valve tappet clearance, and sometimes as valve lash. This clearance allows for expansion of the valve stem as the engine becomes heated.
4, If sufficient clearance is not given, the valve will not seat properly when the engine becomes heat, which will cause power loss and lifting of the valve. It is better to have more clearance than necessary rather than to have too little, in spite of the slight increase in noise of the valve mechanism.
Diesel Engine Description:
1, diesel engine, any internal combustion engine in which air is compressed to a sufficiently high temperature to ignite diesel fuel injected into the cylinder, where combustion and expansion actuate a piston. It converts the cemical energy. stored in the fuel into mechanical energy, which can be used to power freight trucks, large tractors, locomotives, and marine vessels. A limited number of automobiles also are diesel-powered, as are some electric-power generator sets.
2, The diesel engine is an intermittent-combustion piston-cylinder device. It operates on either a two-stroke or four-stroke cycle (see figure); however, unlike the spark-ignition gasoline engine, the diesel engine induces only air into the combustion chamber on its intake stroke. Diesel engines are typically constructed with compression ratios in the range 14:1 to 22:1. Both two-stroke and four-stroke engine designs can be found among engines with boress (cylinder diameters) less than 600 mm (24 inches). Engines with bores of greater than 600 mm are almost exclusively two-stroke cycle systems.
3, The diesel engine gains its energy by burning fuel injected or sprayed into the compressed, hot air charge within the cylinder. The air must be heated to a temperature greater than the temperature at which the injected fuel can ignite. Fuel sprayed into air that has a temperature higher than the “auto-ignition” temperature of the fuel spontaneously reacts with the oxygen in the air and burns. Air temperatures are typically in excess of 526 °C (979 °F); however, at engine start-up, supplemental heating of the cylinders is sometimes employed, since the temperature of the air within the cylinders is determined by both the engine’s compression ratio and its current operating temperature. Diesel engines are sometimes called compression-ignition engines because initiation of combustion relies on air heated by compression rather than on an electric spark.

Premium and Reliable Quality
1- Raw materials:
We only use highest quality primary 21-4N,4CR9SI2 and 40CR.
2- Complete Tests:
The cylinder heads unitary pass by leak test of valves, for water circuit pressure test and oil circuit pressure test.
Checks controls on the machining are made across different steps of the manufacturing process and the results are automatically compared to the specifiafter market dieselions registered in our systems.
Finally, in a unified way, a visual check of the entire piece before packaging is made.
3- ID System:
We have implemented a system of identifiafter market dieselion and trace-ability of our products, which makes possible to correctly identify and separate each and every one of our engine valve.
We also supply Mitsubishi, Toyota, Nissan,Komatsu,Hino,Cummins, , Hyundai,Deutz,heavy duty truck engine cylinder head with high quality and fast delivery time.
