ICEs as Part of Mobile Units: Efficiency Improvement

Abstract:

Paper considers problem of increase in key indicators of the internal combustion engines which are used as a part of a wide range of mobile objects, including motor transport surface, underwater and aircrafts. Approach to the solution of a problem of development of the optimum form of an intake system of the engine providing increase in filling of cylinders with fuel and air mix and uniform distribution of air on cylinders is offered. Besides, the requirement of symmetry in time that means a need of air intake from a throttle to the inlet valve of each cylinder for identical amount of time is put. The results of computing tests of the developed form of an intake collector confirming compliance to the developed model to the given requirements are presented. Model sample intended for installation on small-capacity atmospheric 4-cylinder IC engine is made on the base of 3d-model. Need of modification of the software of a control system of the engine for achievement of the maximum return at tests of a model sample is proved. Corresponding changes are described, comparison charts of adjusting parameters are given. Experimental stand for carrying out natural tests was assembled and used to get the external high-speed characteristic of the engine when using a regular intake collector and intake collector of the developed form. The results of tests that clearly demonstrate increase in power and a torque of the engine are given.
