Results show that under the condition of pressure spray oil lubrication, for the wear of the timing bushing chains, fatigue wear is dominating, and grain wear occurs synchronously.
Activities of EnSpray, a petroleum spray oil, on some insect pests and joint actions of its mixtures were evaluated in the lab.
Combined with the problem of the fuel flow, the friction heat model between diesel fuel and the conduit of the spray oil pump was studied by the method of conservation of energy.
