How automotive engine grows ?

Automotive production down the ages has required a wide range of energy-conversion systems. These include electric, steam, solar, turbine, rotary, and different types of piston-type internal combustion engines. The reciprocating-piston internal -combustion system, operating on a four-stroke cycle, has been the most successful for automobiles, while diesel engines are widely used for trucks and buses.
The gasoline engine was originally selected for the automobile due to its flexibility over a wide range of speeds. Also, the power developed for a given weight engine was reasonable; it could be produced by economical mass-production methods; and it used a readily available, moderately priced fuel–gasoline. Reliability, compact size, and range of operation later became important factors. (more…)

Engine designed for fuel efficient

Fisher Technologies has developed a modern-day performance increase for all piston engines which dramatically improves the efficiency for conventional engines, both gasoline and diesel. This unique cutting edge technology provides substantial increases in fuel economy, significant reductions in exhaust emissions and more power just by adding a “yoke-arm” between the piston rod and power-shaft. A simple mechanical combination, never before developed for piston engines, uses a unique yoke-arm linkage that connects the piston rod to the crankshaft, yet leaves the remaining mechanical arrangement for conventional piston engines relatively unchanged.

Piston engines applies new technology

Finding important break-thru energy innovations to save fuel and money should be one of America’s top priorities. To date, the engine and auto industries have exhausted most avenues to improve the piston engine and little or no consideration has been given to the piston-rod mechanical linkage. Big-Step is a “leap frog” initiative by Fisher Technologies to move forward with a proven, patented linkage and modern-day break-thru for the piston-rod/crankshaft connection substantially improving the performance of conventional piston engines.

Both automobile manufacturers and engine designers historically have been mostly of the mind-set to design and develop “small-step” improvements, and such a mind-set has slowed the progress for discovering the much greater break-thru needed today. (more…)

E30 M3 engine from BMW

The E30 M3 is the BMW Motorsport-developed version of the E30 3 Series. Its S14 four-cylinder powerplant is a further development of the M10 unit and was chosen by BMW because of its compact dimensions. The S14 engine powered the E30 M3 from 1986 to 1991.

The E30 M3′s S14 engine was designed for racing applications and is therefore compact and high-revving. It combines the basic four-cylinder block from the M10 family with a four-valve head derived from the one used on the six-cylinder M88 and S38 motors. Special features of this engine include individual throttle plates for each cylinder, machined intake and exhaust ports, and a crankshaft with eight counterweights. Like the M88 and S38, the S14 does not have hydraulic lifters, and thus requires periodic valve adjustments. (more…)

MINIs was developed jointly by BMW and Chrysler

The MINI Cooper delivers 85 kW/115 bhp (PS), while MINI One has 66 kW/90 bhp (PS). The Pentagon engine meets the EU4 emissions requirements and is one of the few engines on the market that requires no secondary air injection or exhaust re-circulation to achieve this.

The engine has an overhead camshaft with control chain and four valves per cylinder, with roller tip levers that control hydraulic valve balancing elements. The cast iron engine block ensures low levels of noise and vibration. The cylinder head is aluminum.

Active knock control means that the engine runs on lead-free fuel between 91 and 98 octane. The same engine tuning can therefore be used almost anywhere in the world, no matter what fuel grade is available locally. In addition, customers can choose freely if various fuel qualities are available in their market. (more…)

Work of car engines

Have you ever opened the hood of your car and wondered what was going on in there? A car engine can look like a big confusing jumble of metal, tubes and wires to the uninitiated.

You might want to know what’s going on simply out of curiosity. Or perhaps you are buying a new car, and you hear things like “3.0 liter V-6″ and “dual overhead cams” and “tuned port fuel injection.” What does all ­of that mean?

­­In this article, we’ll discuss the basic idea behind an engine a­nd then go into detail about how all the pieces fit together, what can go wrong and how to increase performance.

The purpose of a gasoline car engine is to convert gasoline into motion so that your car can move. Currently the easiest way to create motion from gasoline is to burn the gasoline inside an engine. Therefore, a car engine is an internal combustion engine — combustion takes place internally.

Two things to note:

  • There are different kinds of internal combustion engines. Diesel engines are one form and gas turbine engines are another. See also the articles on HEMI engines, rotary engines and two-stroke engines. Each has its own advantages and disadvantages.
  • There is such a thing as an external combustion engine. A steam engine in old-fashioned trains and steam boats is the best example of an external combustion engine. The fuel (coal, wood, oil, whatever) in a steam engine burns outside the engine to create steam, and the steam creates motion inside the engine. Internal combustion is a lot more efficient (takes less fuel per mile) than external combustion, plus an internal combustion engine is a lot smaller than an equivalent external combustion engine. This explains why we don’t see any cars from Ford and GM using steam engines.

Let’s look at the internal combustion process in more detail in the next section.

Wind-Powered Car Actually Moves Faster Than Wind Speed, Answering Tricky Physics Question

A California team recently tested a wind-powered car that can actually outrun the wind, adding more fuel to a lingering physics debate. In a test two weeks ago, the car hit a top speed 2.86 times faster than the wind, according to its creators. Some physicists say this should be impossible, but car-builder Rick Cavallaro says that’s exactly what happened on May 16. What gives?

Cavallaro had funding from Google and Joby Energy to build the car, basically an aerodynamic foam chassis attached to a wind turbine, with the San Jose State University aerodynamics department.
