Abstract:
A method for starting a primary engine including an air induction system using an exhaust gas stream from an auxiliary engine and a check valve, comprising the step of:conducting the exhaust gas stream from the auxiliary engine to the air induction system of the primary engine; adding fresh air to the exhaust gas stream before the exhaust gas stream arrives at the air induction system as needed to prevent under-pressurizing the air induction system of the primary engine; and reducing the exhaust gas stream pressure before the exhaust gas stream arrives at the air induction system of the primary engine as needed to prevent over-pressuring the air induction system of the primary engine, wherein the step of adding fresh air to the exhaust gas stream before the exhaust gas stream arrives at the air induction system is accomplished using a check valve in line with a conduit conducting the exhaust gas stream from the auxiliary engine to the air induction system.
