IC engine control system - uses EGR and low heat conduction inlet manifold with matching of inlet air to injected fuel volume

摘要

The IC engine load regulator makes use of a device to control the temp of the intake air. A system to reduce heat transfer between air flow and intake line wall should be fitted on the intake line (2) downstream of the device. Pref. the line is made of low heat-conducting material downstream of the device and the line wall here is coated in a heat insulating layer. The device pref. consists of an exhaust return line (4) which issues into the intake line and whose section is controlled by a first valve (5). USE/ADVANTAGE - IC engine intake air flow is adapted to injected fuel volume and thus engine load by temp variation to retain stoichiometric conditions.
