Advantages Of New Technology In Engines

Economical

Less Pollution

More Efficiency

Introduction

New technology in various engine systems such as.

Alternative Fuel

Ignition system

Designs of crankshafts

Valves

Pistons

Aluminium Body

TwinPower Turbo engines

Alternative Fuels

Engine in which the combustion of a fuel (normally a fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. Alternative fuels, known as non-conventional or advanced fuels, are any materials or substances that can be used as fuels, other than conventional fuels. Algae based fuels

Alcohol fuels

Biofuels and vegoils

Air

Hydrogen

Batteries

Variable Valve Timing with intelligence

The shaft spins just like a regular camshaft -- but by gradually sliding the camshaft laterally as the engine speed and load increase, the valve timing can be optimized. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless system

VALVE TRONIC ENGINES

The Valvetronic engine is the world's first engine without a throttle butterfly. Valvetronic varies with the timing and the lift of the intake valves. This valvetronic engines allows the engine to breathe more freely, fuel consumption is reduced by 10%. Valvetronic reduces maintenance costs, improves cold start behavior, lowers exhaust emissions, and provides a  smoother running engine.

Aluminium engine body

An aluminium engine body comprises a main body and the outer cover body A modern car engine with components made of aluminium can be 24 percent lighter than one with components made of steel, which also allows fuel consumption to be reduced by 2 liters per 100 kilometers.

NEW TEFLON PADS PISTONS

The Cummins V28 engines have used a new technology for their pistons- they have two Teflon pads and the pistons also incorporate a cutback headland.

Teflon padded pistons will eliminate cylinder liner water jacket cavitation corrosion and increase cylinder liner life and hence engine life.

Improved oil consumption

Increased piston and cylinder liner life Teflon pad

Cavity In Piston

engine has the combustion chamber cavity in the crown of the piston. This design is called a Mexican Hat piston. This Piston have a wide pressure range, can reach high pressures and the pressure can be controlled without an impact on the rate of flow it assists in creating air turbulence, which mixes the fuel with air during the last part of compression in diesel engines.

VARIABLE COMPRESSION RATIO

Eccentric crankshaft engine:

The motor provides adjustment in 0.1s for decreasing compression ratio and 0.5s for increasing ratio.

The Saab Variable Compression :

optimum compression ratio of 14:1

The compression ratio can be lowered to 8:1 at high load.

FAST SOLENOID COMMON RAIL

which enable multiple injection events, increased injection pressure capability and a new closed loop control system known as Accelerometer Pilot Control (APC). and the system is correctly calibrated. Solenoid valves make possible fine electronic control over the fuel injection time and quantity.

TwinPower Turbo engines

TwinPower Turbo engines are made in lightweight aluminium construction and use variable turbine geometry TwinPower Turbo petrol engines is applied throughout the series. Innovative turbocharger technology and Double-Vanos increase performance and ensure spontaneous response even at low speeds.
