THE FOUR CYLINDER ENGINE (INLINE)

THE FOUR CYLINDER ENGINE (INLINE)

The inline-four engine or straight-four engine is an internal combustion engine with all four cylinders mounted in a straight line, or plane along the crankcase. The four pistons rotate the common crankshaft
This type of engine is very widely used as it has compact build and economical to run but it has its disadvantages mostly being as it runs the pistons move in pairs up and down causing an imbalance in the rotating motion of the shaft hence causing vibrations which in small engines is tolerable but excess in huge engines esp at high speeds.Much of this is controlled using engine mounting with rubber to dampen the effects and also the use of Balance shafts:This are small weighted  shafts driven by the main shaft turning at high speeds in opposite directions to correct the vibrations,they are usually connected by a chain.
The Number of cylinders that an engine contains is an important factor in overall engine performance of the engine hence the  Four cylinder is not the  champion in speed but offers advantages in its low consumption and low emission and with the advances in design a comfortable ride

THE LANDROVER DEFENDER

                                                               
This four wheel vehicle is made by the British car manufacturer part of the Jaguar Land Rover
Group, a subsidiary of Tata Motors of India The land rovers has been in production since 1948,
Different models hitting the market all encompassing different tastes of the four-wheel vehicles.
The Defender is available in both 90 and 110 wheelbases, offering functionality with secure load carrying capability
Defender’s 2.2 litre diesel engine produces an impressive 360Nm of torque. With 90 percent of peak power constantly on tap from as low as 2,200rpm to over 4,350rpm, it provides maximum muscle for tough working environments.

In keeping with the modern advances in fuel and engine technologies, a unique engine tune has been developed which allows it to tolerate the variable quality, high-sulphur fuels to be found across some emerging markets*. To cope with the sort of difficult progress that many operations demand, when the engine is working hard at low speed, around 1,000rpm, Land Rover’s innovative Anti-Stall device intelligently adjusts the fuel required to help keep everything running smoothly.
The Defender’ is a six-speed manual transmission. Specially developed for heavy-duty applications, it is light, strong and also provides smooth on-road performance and slick gear changes. it also comes with a light weight Aluminum body helping it improve on the fuel consumption
*Doors and Bonnets are made from corrosion resistant steel
For maximum control both on and off-road, Defender is available with ABS (excluding 130 models). Detecting any significant difference between wheel speeds during heavy braking, this optional system helps maintain continued progress by automatically reducing brake force to the appropriate wheel. Electronic Traction Control is included in this option.
