What causes black smoke emission within diesel engines?
The most obvious characteristic of a diesel engine is that it uses kerosene as fuel. As you know, it employs the mechanism whereby the fuel is directly sprayed and lighted in a high pressure & high temperature (approximately 500C) atmosphere. Hence it can use the cheaper kerosene because it does not need to vaporize the fuel, as opposed to gasoline engines which use gasoline. However, there is major problem in using kerosene that the sulphur contents in the kerosene burns to product sulphuric acids as part of the products, and the acid corrodes the major parts in the engine. Therefore, diesel engines requires special-purpose oils with reinforced acid-neutralizing properties. As TOHO ENGINE OIL is a high-tech superb engine oil treatment for base oil, it can provide special characteristics i.e. “Durable to heat”, “Acid proof”, “Cooling Agent”, “High cleansing capabilities”, “Disperses oil impurities” and “Long lasting neutralizing effect”. Once diesel engine uses TOHO ENGINE OIL, it will
