摘要： Variations in the air-fuel ratio among cylinders are specified as one cause of deterioration in exhaust emissions however the size of the variations in the air-fuel ratio among cylinders detected by the catalyst upstream sensor does not always match the margin of deterioration in exhaust emissions. The objective of the present invention is to detect the deterioration in the exhaust emissions caused due to variations in the air-fuel ratio among cylinders. Deterioration in exhaust emissions due to variations in the air-fuel ratio among engine cylinders is detected based on a means to calculate a specified frequency component A of the catalyst upstream sensor signal; a means to calculate a specified frequency component B of the catalyst downstream sensor signal; and the frequency component A and the frequency component B.

摘要： An engine system is capable of switching between a first fuel injection mode, in which fuel is injected from a fuel injection valve 23 directly into a combustion chamber 6 in the compression stroke, and a second fuel injection mode, in which fuel is injected from the fuel injection valve 23 directly into the combustion chamber 6 in the intake stroke. A controller 30 determines the characteristic of the fuel that is supplied to the fuel injection valve 23, selects either the first fuel injection mode or the second fuel injection mode according to the fuel characteristic, and starts an engine 1 in the selected fuel injection mode.

摘要： Motor vehicles of all types with various forms of drive have been known for some time. For the propulsion thereof, said vehicles regularly burn fluid fossil fuels, such as for example, derivatives obtained from crude oil, like diesel, petrol and similar, which may also be treated with additives. The application of said fossil fuels in motor vehicles causes various pollutants, such as for example, carbon monoxide, nitrogen oxide, carbon dioxide and particulates etc. The aim of the invention is to reduce at least one harmful component on burning fossil fuels of all kinds, keeping the applied technological complexity to a minimum. Said aim is achieved with the use of an information support of the ENERCON type in a vehicle, whereby the information support is preferably mounted at a close distance and/or with the largest possible surface and/or contacting with the motor block and/or fuel tank and/or fuel line and/or the air conditioning unit and/or another part of the interior of the motor vehicle.
