How Did Valvetronic Engine Technology With BMW Become The Best

How Did Valvetronic Engine Technology With BMW Became The Best….

A Preview Of Concept

Enjoy better performance

while consuming less

fuel: Valvetronic lets you get even more

driving pleasure from

your BMW engine

Valvetronic is an engine technology that

developed the first

production petrol engine

in the world no longer

requiring a throttle butterfly.

Throttle ButterflyThrottle is a mechanism by which the power or speed of an engine is regulated

It helps to Obstruct the free ventilation of the petrol engine throughout a wide range of operation…………

Inventions Got Modified

BY Technology

The Valvetronic engine replaces the function of the throttle butterfly by using an infinitely variable intake valve lift .

INVENTED BY BMW………..in

2001

The invention …………..

From the distributor-type

injection pump to common

rail technology, from

mechanical to electronic

engine management.

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 new BMW E65 7

Series with

Valvetronic engines.

Advantages

over Throttle

…………. follows

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)

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 to notify the about any

problem.

Experience what innovation feels like………

Significant decrease in

fuel consumption

combined with much lower

exhaust emissions

VALVETRONIC offers direct, immediate benefits, with fuel consumption and exhaust emission decreasing, but dynamic performance and the spontaneous response of the engine improving accordingly..

Valvetronic reduces

maintenance costs, improves

cold start behavior, lowers

exhaust emissions, and

provides a smoother running of

engine

Much better engine

response and

superior refinement

Valvetronic helps higher

standard of running

smoothness, since the valves

move slightly in a precisely

controlled process.

Valvetronic does not need specific fuel grades or fuel qualities because of its fine atomization of fuel.

VALVETRONIC highly beneficial to the customer with the VALVETRONIC engine it offers at least the high fuel economy with limited emission.

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…………

In A DEEPER Look Into

BMW ENGINE

Engine’s main function is the

process of controlling of the gas

charge cycle that has always

been a compromise between

output and torque in one hand

fuel consumption, emissions and

comfort on the other hand.

THE CURRENT TECHNOLOGY

USED BY BMW……………

Partly variable valve control

currently culminating in BMW

double-VANOS (variable camshaft

angle control)

WHY New

Invention takes

place……………………..?

Control engine out put

Control the waste of fuel and power

Control the ventilation of petrol engine

Taking Nature as a Role

Model…………….HOW……

………………….?

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.

Basic Engine Design

Completely REVISED by the

Introduction of Valvetronic

ENGINE

Anti-knock control for

running on all fuel grades

between 87 and 99 octane.

Octane is the standard measure of

performance of fuel

The implementation of valvetronic technology

increases the fuel performance of BMW as per

the octane rating .

Maintenance-free Ignition System With Individual Coils.

Valvetronic system introduces

individual coil for each cylinder

that reduces the saturation time

for hotter spark and specially at

higher rpm when firing times are

greatly reduced. The result is

fewer misfires, cleaner combustion

and better fuel economy

Maintenance-free valve drive

with hydraulic valve play

compensation

Hydraulic valve play compensation is a device for

maintaining zero valve clearance in an internal

combustion engine. But in the application of

Valvetronic , it eliminates the need for periodic

adjustment of valve clearance.

A Service Interval Indicator to

keep the cost of service to a

minimum

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 .

Advanced catalysts near the engine in

special manifold design for minimum

emissions.

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