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…………
The Work Process

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)

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.
