At the running of kerosene engine by gas oil, heating of mixture is very effective in light load, but in heavy load knocking combustion occurs and engine performance is lowered. we researched the effect of water injection on the knocking at such a state, changing the air-fuel ratio and water quantity injected. It was found that knocking was suppressed, power output or thermal efficiecy was increased respectively by about 10% as a result of injecting a proper amount of water in the suction pipe. Water injection was most effective for rich mixture. In case of non-heating of mixture, water injection was equally effective for knocking.
