As a connecting rod is rigid, it may transmit either a push or a pull and so the rod may rotate the crank through both halves of a revolution, i. Pressure and temperature are two of the most important factors to be considered before selecting the type of material to be used. Next Story Biggest Innovation: They are not rigidly fixed at either end, so that the angle between the connecting rod and the piston can change as the rod moves up and down and rotates around the crankshaft. The process of mixture preparation is extremely important for spark ignition engines. Stroke is defined as the distance traveled by the piston from one of the dead centers to the other dead centre.

At higher speeds the over boost will enhance full power delivery and will stay on as long as the driver exercises maximum pressure on the accelerator. It is a means of controlling the ignition by operating the throttle. These experiments, with the benefit of hindsight, seem self-evident. According to you which one is more efficient, four stroke engine or a two stroke engine and why? Modeling, analysis and simulation of a digital twin spark injection system. That is all thanks to its success in creating the performance segment – where it refuses to get into a price war and enjoys high margins – and in becoming India’s largest exporter of motorcycles by a long yard. Hence forth there was a requirement to change engines’ design, fuelling, ignition, production and quality to achieve the following objectives.

A Digital CDI with an 8 bit microprocessor chip handles the spark delivery. The Japanese company dts provided technical drawings, which Bajaj had to put to use at its factories through its own processes.

The problem-based learning PBL movement offers an example. A six stroke engine works similarly except that there are two power strokes. Due to Sthdy Twin Spark Ignition System it is possible to combine strong performance and higher fuel efficiency. Depending on the needs of the Rider whether it be cruising, acceleration or max speed, the ignition requirements constantly change. It is not a trivial thing like making a hole and putting a spark plug in it,” says V. vtsi


Yamaha’s motorcycles, made with Escorts, were known for their performance. A fast rate of combustion is achieved leading to faster rise in pressure. And those who doubted them back then turn their faces away stuey, like the Pulsar’s headlight turned to passing girls in its television commercial, as a gravelly voice said: There are some advance technology sgudy in DTS-i engine which makes it more powerful than the conventional single sparkplug 4-stroke engine like 1.

Failure of either circuit will not stop the engine, which can still work with single spark ignition. Detonation occurs when the flame travel time from center to the side walls increases the self ignition temp.


Biggest innovations: How two mechanical engineers did magic with spark plugs for Bajaj DTSi

Fuel droplets which remain in suspension continue to evaporate and mix with air even during suction and compression processes. It is typically connected to a flywheel to reduce the pulsation characteristics of the four — stroke cycle, and sometimes the torsional or vibratioal damper at the opposite end, to reduce the torsional vibrations often Caused along the length of the crankshaft by the cylinder farthest from the output end acting on the torsional elasticity of the metal.

Playing With Fire That is what the combustion chamber of an engine is: The benefits of this efficient combustion process can be felt in terms of better fuel efficiency and lower emissions.

Connecting rods, especially in racing engines, may be called “billet” rods, if they are machined out of a solid billet of metal, rather than being cast or forged.


Bright Sparks

The portion of the hole where the plug meets with it is referred as the ‘seat’ or ‘valve seat’. A Digital CDI with an 8 bit microprocessor chip handles the spark delivery. That would be the tweet to stduy the story of how Bajaj Auto became the world’s first company to make two-wheeler engines with two spark plugs in the combustion chamber. Its main characteristics are: Instead, he read and read: Mileage kmpl kmpl 5.

emgine Pulsar proved the sceptics wrong from the start. The main components of DTS-i engine 5. Digital spark technology is currently used in Bajaj motor cycles in India, because they have the patent right.

It consists of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem.

Some of the burnt gases are however left in the clearance space. So for the instantaneous burning of fuels in I. Random and large samples were at no time part of the case.

In fact, for better power and fuel efficiency, they must burn variably in relation to each other depending on the temperature outside, the speed of the vehicle, and the load on it. Its operation is controlled by the electronic control box of the integrated ignition and fuel injection system. The second, the slave spark, follows it after a delay.

Popper himself used the now famous example:
