Condensation control for internal combustion engine having an exhaust gas recirculation circuit

A system and method for controlling an internal combustion engine to reduce or eliminate formation of EGR condensate is disclosed. Said method comprises monitoring current ambient 200 and engine operating conditions 210 and determining whether conditions are favourable for condensation of the EGR gases 222. If said conditions are favourable the engine is controlled accordingly 228 to avoid condensation; preferably by increasing the intake manifold temperature. The intake manifold temperature may be increased by redirecting some or all of the EGR flow 230 to avoid an EGR cooler. Alternatively, or in combination, some or all of the charge air may be redirected 232 to bypass the charge air cooler and/ or redirected from the outlet of a turbocharger compressor to the intake, effectively increasing the intake air temperature and resulting in a corresponding increase of the intake manifold temperature. Conditions favourable for condensation may be determined based on engine speed and load 214 ...

Air-cycle refrigerated boosted intercooling of i.c. engines

Boosted intercooling requires high pressure turbocharging such that with a much higher charge air temperature the intercooler removes much more heat than conventionally. This extra cooled, over-boosted charge air, eg from compressor 2 of a turbocharger via an air-air intercooler 4, is air-cycle refrigerated by pressure reduction via an expander (cooling) turbine/reverse-acting supercharger 7, that outputs power at output shaft 9 when 'braked' via an underdriven belt-and-pulley drive to the engine crank, or a generator plus battery pack. A CVT belt drive enables a positive displacement supercharger to be operated as a throttle such that at less than WOT/underdrive conditions engine vacuum pressure drives the supercharger causing expansion cooling and reducing engine idle rpm. Expansion cooling allows high turbo boost pressures that extract more exhaust energy resulting in expander power output that increases fuel economy and power. High boost charge air temperatures may require face-split ...

Condensation reduction in the exhaust gas recirculation (EGR) system of a compression ignition i.c. engine based on humidity

The exhaust gas recirculation is shut off depending upon the sensed or calculated humidity in the intake manifold relative to the dew point of the exhaust/intake air mixture. The humidity of the exhaust/intake air mixture may be measured in the intake manifold, charge air mixer or the ambient humidity may be sensed. If humidity is measured in the air charge mixer or in the ambient air, other factors such as engine speed and load, intake manifold pressure, EGR flow and air/fuel ratio may be used to calculate the humidity in the intake manifold. When the temperature of the mixture in the intake manifold is less than the dew point of the mixture, the engine control strategy may be shut off the EGR to prevent condensation in the exhaust gas recirculation system or engine.

INTERNAL COMBUSTION ENGINE AND METHOD

Disclosed are methods of and means for an improved internal combustion engine performance and of substantially reduced or eliminated pollutants. A relatively slow and long burning combustion is provided which produces an exhaust of high pressure which can be utilized to drive a turbocharger or cylinder or subsequent cylinders. Ideally, the compression ratio is reduced with respect to current internal combustion engines, and the maximum temperature in the power or combustion cylinder can be below the temperature at which NOx is formed. Preferably the pressure during combustion remains substantially constant and the air or air/fuel mixture is externally compressed 40 to 100% of its compression pressure in the combustion cylinder. This results in a controlled energy release tailored to a change in volume per unit of time which results in more torque and horsepower, less fuel consumption and drastically decreases pollution, both chemical and heat to the atmosphere.

Supercharging pressure controller for engine

A supercharging pressure controller of an internal combustion engine estimates time to execute a process of bringing power supplied to an assist motor to zero based on delay characteristics of actual emission energy immediately before actual supercharging pressure reaches target supercharging pressure. The supercharging pressure controller sets a gradient of a power gradual reduction waveform in a power gradual reduction control period at a gradient for bringing the power supplied to the assist motor to zero at the estimated time. Thus, the power supplied to the assist motor gradually reduces at the predetermined gradient over time finally to zero at the estimated time. The assist motor is turned off while the actual supercharging pressure follows the target supercharging pressure, without wastefully consuming electric energy.

Exhaust gas recirculation in a homogeneous charge compression ignition engine

A homogeneous charge compression ignition engine operates by injecting liquid fuel directly in a combustion chamber, and mixing the fuel with recirculated exhaust and fresh air through an auto ignition condition of the fuel. The engine includes at least one turbocharger for extracting energy from the engine exhaust and using that energy to boost intake pressure of recirculated exhaust gas and fresh air. Elevated proportions of exhaust gas recirculated to the engine are attained by throttling the fresh air inlet supply. These elevated exhaust gas recirculation rates allow the HCCI engine to be operated at higher speeds and loads rendering the HCCI engine a more viable alternative to a conventional diesel engine.

Therefore, in the present invention, a pipe 130 connecting the exhaust manifold 120 and the intake manifold 110 installed in the engine main body 100 is installed, and the intake manifold 110 and the pipe 130 are connected to the site. An air chamber 140 in which the exhaust gas is stored or discharged is formed, and the air chamber 140 is provided with a solenoid 150 for blocking or introducing the exhaust gas introduced through the exhaust manifold 120. The solenoid 150 is to provide a structure connected to the electronic control unit 160 (ECU) as this invention can prevent overheating of the vehicle.

The train has an exhaust gas recirculation (EGR) circuit (54) with an EGR valve (44) and control valves (80, 82). A controller (88), based on a signal representative of exhaust gas output temperature in cooled or non-cooled recirculation, selectively controls the valve (44) to control the flow of exhaust gas in the circuit, and the valves (80, 82) to adjust the temperature of the gas in the circuit. The EGR valve controls the recirculation of exhaust gas to an internal combustion engine (12), and the control valves (80, 82) selectively direct the gas to by-pass channels (72, 78) and/or upstream, intermediate and downstream sections (66, 68, 70).
