Technical Examples

An exhaust gas recirculation cooler, typically of the drawn cup design, with a bypass and control valve is disclosed. The control valve can direct a proportion of the exhaust gas to the cooler and a proportion to bypass the cooler depending on the input temperature of the exhaust gas and the required temperature of the exhaust gas. The proportion of the exhaust gas directed to the cooler/bypassing the cooler can be varied as required and so the temperature of the exhaust gas can be controlled. One benefit of certain embodiments of the invention is that engine damaging chemicals, such as sulphuric acid, which result from over-cooling the exhaust gas are reduced.
