Valve corrosionAbstract
Valve is one of the components in the Mitsubishi Triton engine which has a very vital role, the valve functions to open and close the combustion chamber and to disconnect and connect the combustion chamber with outside air when needed. Valve damage has a significant impact on the power generated by the engine. This study aims to find out the cause of weight loss due to corrosion in the Mitsubishi Triton 2.5 CC engine unit. This study used four valves and measured the weight of the valve to determine the standard limit for weight reduction due to the corrosion rate of 48.7 gr of valve standard value on the entire valve weight using digital scales carried out at the PT Alat Bumi Permai Balikpapan Workshop. Based on the results of research and analysis carried out, there is a cause in this case where dust particles that cannot be filtered properly by the air filter so that the dust accumulates in the combustion chamber attached to the valve, incomplete combustion in the combustion room makes a pile of carbon crust. The higher the KM of the component, the higher the corrosion rate and weight loss of the valve. Judging from the standard weight of the new valve 48.7 gr, the standard diameter on the valve rod is 6.09 mm. The last unit kilometer is 92, 145 KM. 48.7 gr new valve standard value with an average valve corrosion rate of 0.9 gr with a unit kilometer of 92,145 KM. 48.7 gr – 47.8 gr = 0.9 w/ 2,5 gram for weight loss. Where the corrosion rate is 0.9 gr: 48.9 gr the valve is corroded before cleaning = 0.018404908 gr x kilometers unit 92,145 KM = 0,92792446687 gram/second resulting from the corrosion rate at kilometers 92,145 KM.
