An air boost system for a two-cycle engine, such as an EMD engine, which operates with one or more roots blowers, or for similar engines that use gear-driven roots blowers or centrifugal blowers. At least one of the roots blowers is equipped with a variable transmission, which allows airflow into the engine to be varied in accordance with load or other engine operating conditions.

An internal combustion engine includes a cylinder case that includes a first geartrain disposed on a front end of the cylinder case and a second geartrain disposed on a rear end of the cylinder case. The first geartrain drives a first camshaft, and the second geartrain drives a second camshaft, the first and second camshafts having respective rotational axes that are parallel.

An engine system may include an engine including first and second cylinder banks; a throttle valve; a first exhaust manifold gathering exhaust gas exhausted from the first cylinder bank to be supplied to the first exhaust line; a second exhaust manifold gathering exhaust gas exhausted from the second cylinder bank to be supplied to the second exhaust line; a turbocharger including a turbine rotated by the exhaust gas exhausted through the first exhaust manifold and a compressor rotated in connection with the turbine; a cylinder deactivation (CDA) device selectively deactivating the cylinders of the first cylinder bank; and a supercharger including a motor and an electric compressor operated by the motor.
