【 摘 要 】

Modern combustion engines development is targeted on respect of environment protection. Engine constructor main task is lowering toxic substances emission in exhaust. This trend is the same for CI and spark ignition engines. Toxic substances content in exhaust depend on many factors like combustion chamber construction, the sort of fuel and inlet system, fuel - air mixture organize process, the sort of fuel and engine work environment. It was very important period in motorization development implementing electronic engine work steering systems. The factors influence on emission in exhaust analysis shows that there is possibility reduce toxic substances in fumes through correct organizing fuel - air combustion mixture in CI - engine. The injecting fuel streams parameters influence on combustion mixture forming process. The article presents fuel injector modification concept. The aim of modern fuel injector modification is improvement of fuel stream parameters like range, width, atomization and obtuse angle. The performing researches show that making changes on non - working needle part influence especially on particles and carbon monoxide emission.
