Abstract: A method and system for controlling engine temperature by derating torque output of the engine. The method and system operate in cooperation with an electronic control module which is programmable for controlling temperature in the engine by derating maximum engine torque output based on an engine temperature rate of change. This permits the derating to be finely tuned to maximize available torque.

Abstract: A control for an internal combustion engine that includes an exhaust gas recirculation system predicts at least one of the intake manifold temperature in EGR mode or an intake manifold pressure in EGR mode, but preferably both, during Boost mode operation. The predictions are relied upon to calculate an intake manifold critical temperate in EGR, at which condensation would occur. The control then compares the predicted temperate value with the calculated intake manifold critical temperature, and if the predicted value exceeds the calculated temperature, the control commands re-entry into exhaust gas recirculation mode.

Abstract: An exerciser includes a base, a post extending upright from the base, a lever pivoted to and extending transversely from the post, a resistance providing member interconnecting the base and the lever, an upper pulley mounted rotatably on a free end of the lever, a lower pulley mounted rotatably on the base, and a string fixed to the base, extending upwardly from the base and over the upper pulley, and downwardly from the upper pulley and over the lower pulley so as to permit rotation of the lever when the string is pulled away from the lower pulley.

Abstract: An internal combustion engine includes a block having a plurality of cylinders. An intake manifold is fluidly connected to the block for supplying charge air to the cylinders. An exhaust manifold is fluidly connected to the plurality of cylinders for conducting exhaust gas away from the cylinders. A turbocharger including a turbine having an exhaust gas inlet is fluidly connected with the exhaust manifold. The turbocharger also includes a compressor having a compressor air inlet and air outlet. The compressor air outlet is fluidly connected to the intake manifold to pressurize the charge air during high power levels of engine operation. An EGR bypass is fluidly connected between the turbine exhaust gas inlet and the intake manifold to recirculate a portion of the exhaust gases to the cylinders. An intake air bypass is fluidly connected between the compressor air outlet and the compressor air inlet.

A turbocharger including a turbine has an exhaust gas inlet connected with the exhaust manifold and also includes a compressor having an air inlet and outlet. The compressor air outlet is connected to the intake manifold to pressurize charge air during high power levels of engine operation. An EGR bypass connected between the turbine exhaust gas inlet and the intake manifold recirculates a portion of the exhaust gases to the cylinders. An intake air bypass adapted to recirculate a portion of compressor outlet air back to the compressor air inlet to reduce compressor outlet pressure and aid EGR flow through the EGR bypass to the cylinders during high power operation of the engine is connected between the compressor air outlet and the compressor air inlet.
