Technology

OLD Technology Replaced By New One

Valvetronic on the all-alloy 1.8-

liter, 4-cylinder engine for the

E46 316ti Compact

implemented 12-cylinder

engines in BMW.

The Valvetronic engine does not

require a timing belt or chain.

Valvetronic has its own computer

housed in a separate unit away from the

engine management system,

( It works the networked with the

digital engine management system

incorporating a 40-megahertz, 32-bit

computer)

Experience what

innovation feels like………

VALVETRONIC offers direct, immediate benefits, with fuel consumption and exhaust

emission decreasing, but dynamic performance and the spontaneous response of the

engine improving accordingly..

THE Future Plans…. ………..

Valvetronic system is claimed to reduce fuel

consumption by at least 10%

The most significant and outstanding technology

used by BMW for achieving the demanding EU fuel

economy targets specified for the future

Requiring a reduction of fleet consumption to 140

grams of CO2 per kilometer by the year 2016

To give as many BMW owners as possible the advantages of the

Valvetronic system, BMW's 8 and 12-cylinder power plants will

also be converted to this technology this year.

Not in specified models of BMW but also in all models this

technology introduced.

This change in engine generations that is deemed to be the

largest engine project ever throughout the entire history of BMW.

FUTURE PLANS FOR MARKET AS FOLLOWS…………

Control engine out put

Control the waste of fuel

and power

Control the ventilation

of petrol engine

Whenever we are making a great physical effort, we breathes in a deep and long process of ventilation. Whenever we need less air, on the other hand, we do not 'throttle' the intake of air by, say, holding his nose or mouth, but rather simply breathe in a shorter and "flatter" process.

In the conventional combustion engine, the throttle butterfly is basically comparable to a human being holding his hand over his nose or mouth. Valvetronic, in turn, with its valve lift sometimes larger (deep, long ventilation) and sometimes smaller ( flat, short ventilation) allows the engine to breathe like a human being in nature.

Always taking up air in accordance with current requirements, without any throttle effect and therefore with maximum efficiency.

Maintenance-free Ignition System With

Individual Coils.

A service interval is mostly based on oil change for better fuel efficiency in cars

like BMW. As Oil is commonly referred as the life-blood of an engine and also a

Proper lubrication is tantamount to an engine's health, so you need to regularly

replace your engine oil and oil filter. But application of Valvetronic increase the

fuel efficiency as it reduces the cost of service .

The first objective is to minimize emission components such as hydrocarbons. For this, valvetronic has introduced advanced catalysts near the engine to minimize emission.
