Systems and methods for migitating emissions generated by hybrid vehicles

Abstract

An ICE emission mitigation signal is received prior to normal operation of an ICE of a hybrid vehicle. A command is issued to at least partially open a throttle to enable air flow into an intake manifold. A command is issued to an electric motor system to rotate a crankshaft coupled to each of the cylinders. The reciprocating motion of a piston in each cylinder compresses air in a combustion chamber of the cylinder causing compressed air to flow out of the combustion chamber. The air flowing into the combustion chamber has a first temperature and the compressed air flowing out of the combustion chamber has a second temperature. The second temperature is higher than the first temperature. The compressed air flows from the combustion chamber of the cylinder to an exhaust manifold via an exhaust valve of the cylinder and from the exhaust manifold through a catalyst brick.
