four wheel independent suspension

The chassis of a four wheel independent suspension car must be able to handle the engine power installed. Ever-improving acceleration, higher peak and cornering speeds, and deceleration lead to significantly increased requirements for safer chassis. Independent wheel suspensions follow this trend. Their main advantages are: little space requirement; a kinematic and/or elastokinematic toe-in change, tending …

hybrid pickup truck

Mitsubishi have been prominent in hybrid pickup truck manufacture and have recently developed a heavier, municipal, version of the light hybrid truck launched in 1995. Because added cost limited market acceptance of the lighter, Canter-based, hybrid the decision to build a heavier municipal version, below Figure was taken on the grounds of low noise, and …

cng electric hybrid vehicle

Smaller buses (cng electric hybrid vehicle) have been built with pure electric and alternative forms of hybrid drive. An interesting project by Unique Mobility in North America put a CN Gelectric hybrid system into a 25 ft (7.62 m), 24 passenger vehicle . Here the compactness and locational flexibility of the hybrid-drive elements meant that …

hydrogen powered cars

hydrogen powered cars have a significant potential to reduce emissions from the transportation sector, because they do not emit any greenhouse gases (GHGs) during vehicle operation. Their lifecycle GHG emissions depend on how the hydrogen fuel is made A future mid-size car in the 2035-2045 time frame, powered by fuel cells and using hydrogen generated …

how electric cars work

Electric cars and how work were prevalent in early 20th century, when electricity was preferred in automobile propulsion. Advances in internal combustion technology, especially the electric starter, the greater range of gasoline cars, quicker refueling times, and growing petroleum infrastructure, along with the mass production of gasoline vehicles reduced prices of gasoline cars to less …

control modes for fuel control

The engine control system is responsible for control modes for fuel control and ignition for all possible engine operating conditions. However, there are a number of distinct categories of engine operation, each of which corresponds to a separate and distinct operating mode for the engine control system. The differences between these operating modes are sufficiently …

digital engine control

In fact, most modern engine control systems, s are digital. A typical engine control system incorporates a microprocessor and is essentially a special-purpose computer (or microcontroller). Electronic engine control has evolved from a relatively rudimentary fuel control system employing discrete analog components to the highly precise fuel and ignition control through 32-bit (sometimesmore) microprocessorbased integrated …

unburnt hydrocarbons

unburnt hydrocarbons in the exhaust are the principal cause of the unpleasant smell of a diesel engine, though the lubricating oil also makes a small contribution. There are three main reasons for this. First, at low temperatures and light loads, the mixture may be too lean for efficientburning so the precombustion processes during the ignition …
