Increasing the consumption of fuel in power and automobile sector, increase the pollution of the environment. Smoke and NOX are main pollutants of emission from diesel engine and it is very difficult to control them simultaneously Petroleum based fuels is a finite resource that is rapidly depleting. Consequently, petroleum reserves are not sufficient enough to last many years. Biodiesel is one of the alternative fuel made from vegetable oil, friendly for environment and has no effect on health and can reduce the emission compared with diesel fuel. In this paper will be examined the use of diesel-hibiscus oil mixtures on (a single cylinder, direct ignition, four stroke, vertical, water cooled, naturally aspirated, variable compression ratio diesel engine). For those mixtures at B15 and B25 at compression ratios 13.5:1, 16.5:1 and 18:1 the brake thermal efficiency, mechanical efficiency and exhaust gas temperature. The gas emissions of carbon monoxide (CO), carbon dioxide (CO2) and nitrogen oxide (NOX), are being measured.
