Five-stage electric starter

Abstract

This article classifies and analyzes the existing electric starters, their advantages and disadvantages. A five-stage starter is proposed which improves performances of engines of land vehicles. Operation of the five-stage electric starter is discussed, ray path diagrams are presented for its two internal parameters: K = 4 and K = 1.62, variation of the internal parameter K leads to variation of kinematic properties of the electric starter with planetary reducer. The five-stage starter is intended for expansion of performances of land vehicles. The formulated target is achieved by starting cold engine with high viscosity motor oil at low rpm, and by increase in rpm of crankshaft for preliminary oil supply to friction units before engine start which takes place under optimum conditions.
