What Is a Hybrid System? A hybrid system combines different power sources to maximize each one’s strengths, while compensating for the others’ shortcomings. A gasoline-electric hybrid system, for example, combines an internal combustion engine’s high-speed power with the clean efficiency and low-speed torque of an electric motor that never needs to be plugged in. Are All Hybrids Created Equal?

Today, various automobile parts are made from plastics, which are reliant on the supply of petroleum. There is a need to find new materials for these parts so we can promote a post-petroleum era and reduce CO2 emissions. The automobile industry’s first plant-derived bio-plastic, which can be injection-molded to ensure thermal and shock resistance and a beautiful finish. High Strength

DISI includes a whole new set of innovations for gasoline engines. To mention a few, direct injection (including cooling the air-gasoline mixture), a new combustion chamber geometry, variable timing technology, and nanotechnology for the catalyst. This all makes the engines consume 20 percent less while getting 15 to 20 percent better performance. Further developments for its diesels: new direct injection

Electronic control common rail type fuel injection system drives an integrated fuel pump at an ultrahigh pressure to distribute fuel to each injector per cylinder through a common rail. This enables optimum combustion to generate big horsepower, and reduce PM* (diesel plume) and fuel consumption. Bosch will supply the complete common-rail injection system for the high-performance 12-cylinder engine introduced by

This hydrogen engine takes advantage of the characteristics of Mazda’s unique rotary engine and maintains a natural driving feeling unique to internal combustion engines. It also achieves excellent environmental performance with zero CO2 emissions. Further, the hydrogen engine ensures performance and reliability equal to that of a gasoline engine. Since the gasoline version requires only a few design changes to

Weight has a significant effect on a vehicle’s basic ability to go, corner and stop. Furthermore, environmental and economic factors such as fuel economy are also strongly influenced by vehicle weight. Mazda strives to minimize the weight of every car it develops. The all-new Mazda2 (Demio) launched in July 2007 is a perfect example. During development, each individual part was

Highlights of the SKYACTIV technologies: SKYACTIV-G: a next-generation highly-efficient direct-injection gasoline engine with the world’s highest compression ratio of 14.0:1 SKYACTIV-D: a next-generation clean diesel engine with the world’s lowest compression ratio of 14.0:1 SKYACTIV-Drive: a next-generation highly-efficient automatic transmission A next-generation manual transmission with a light shift feel, compact size and significantly reduced weight A next-generation lightweight, highly-rigid body
Read moreWhat is the function of EGR valve EGR means Exhaust Gas Recirculation. The main function of EGR is to control NOx emission from the engine. At elevated temperature (during long run & full condition)if due to some reasons engine gets heated up beyond certain level… it produces NOx emission. In order to avoid this pollution , we have to control

In automobile catalytic converters, the surface conditions of the precious metals—the catalyst materials—have a large effect on their ability to clean emissions. Conventionally, precious metal particles are adhered to a base material. However, heat from the exhaust gas causes the particles to collect together and agglomerate to form larger particles. This reduces the surface area of the precious metals and

The key to improving fuel efficiency lies in raising an engine’s thermal efficiency. This can be done by increasing the expansion ratio. The expansion ratio is the amount of work the engine does each time the air-fuel mixture in the cylinders detonates. However, in conventional engines the expansion ratio is the same as the compression ratio, so increasing the expansion
