Abstract
A vehicle includes an internal combustion engine, an air intake coupled to the internal combustion engine and configured to intake air and supply the air to the engine, a temperature controller coupled to the air intake and to the internal combustion engine, and a control system coupled to the air intake, the internal combustion engine, and to the temperature controller. The control system being configured to receive engine operating data and control a temperature of the air via operation of the temperature controller to control an operating condition of the engine.
Claims28
A vehicle, comprising:
- an internal combustion engine;
- an air intake passage coupled to the internal combustion engine and configured to intake air and supply the air to the engine;
- a temperature controller coupled to the air intake passage and to the internal combustion engine, wherein the temperature controller includes:
- a heat exchanger including a heating fluid configured to transfer heat to the air, wherein the heating fluid receives heat from an exhaust gas of the internal combustion engine;
- a temperature adjustment duct configured to direct air from the air intake passage to the heat exchanger;
- a bypass duct configured to direct air to the internal combustion engine at an ambient air temperature such that the air combusts at least partially in combination with a fuel;
- and
- a valve located at a junction of the temperature adjustment duct and the bypass duct and configured to control a first portion of air flowing through the temperature adjustment duct and a second portion of air flowing through the bypass duct based on at least one of an engine power requirement and an intake air temperature;
- a sensor configured to acquire and transmit engine operating data;
- and
- a control system coupled to the air intake passage, the internal combustion engine, the temperature controller, and the sensor, wherein the control system is configured to:
- receive engine operating data, and
- control a temperature of the air based on the engine operating data via operation of the temperature controller to control an engine operating condition.
