New technologies in engines can provide economic, environmental, and efficiency benefits. These technologies include alternative fuels that are less polluting than conventional fuels, advanced ignition and fuel injection systems, new piston and valve designs, and lighter aluminum engine components. Variable valve timing, compression ratios, and turbocharging optimize engine performance for different operating conditions. Overall, the new technologies enhance engine efficiency and reduce emissions.

3. Introduction
New technology in various engine systems such as.
 Alternative Fuel
 Ignition system
 Designs of crankshafts
 Valves
 Pistons
 Aluminium Body
 TwinPower Turbo engines

4. 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

5. 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

6. 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.

7. 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.

8. 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

9. 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.

10. 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.

11. 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.

12. 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.
