Emissions Of Harmful Substances

A method for determining of mechanical losses in an internal combustion engine is proposed, the principal difference of which is the rotation of the engine shaft with compressed air. This method provides high reliability results on reduction of fuel consumption and emissions of harmful substances. Keywords ICE, mechanical losses, tests, compressed air [email protected]

The World

The automotive industry represents one of the most important segments of the world economy that has to be in a continue development. The latest procedures for determination of an internal combustion engine performance have a big acquisition cost and demand special conditions even if the tested engine has smaller dimensions. The present paper presents other accessible solutions for this matter.

The paper substantiates a method for increasing the accuracy of determining the optimal fre-quency of maintenance of one of the most important units of automotive equipment operating in various climatic and road transport conditions - its engines, and also presents circuit proposals for the implementation of this method. The proposed approach makes it possible to significantly increase the accuracy of determining the optimal frequency of maintenance of internal combustion engines by taking into account their real technical condition when operating in different (different from the average) operating conditions. The article provides typical examples of calculating the determination of the optimal frequency of maintenance of automotive equipment, and also estimates the gain achieved when using the approach proposed in the work.

Prototype Measurement

A new technique was devised to deal with real-time fuel consumption measurement in internal-combustion engines, where fuel circulation flow is much larger than the consumption rate. With extensive experiments and error analysis method, the fuel mass flow measurement had been realized by a improved turbine flow sensor with temperature compensation. The real-time accurate fuel consumption measurement had been achieved through data processing and real flow parameter matching method. The results showed that the prototype measurement precision was 1.0 class, satisfying practical measurement requirements.
