RESEARCH PAPER ON DTSI ENGINE

The concept of dual plug spark ignition is under consideration for more than three decades. When the triggering circuit receives triggering signals, the triggering circuit stops the operation of the charging circuit, allowing the capacitor to discharge its output rapidly to the low inductance ignition coil. A pressure at this instant forces about complete the burnt gases into the exhaust manifold at high speed. Electronic control Unit gives accurate timing for all operating condition. Also it is flexible enough in mounting location. To start with the piston is at or very near T.

First, the system voltage is raised up to to volts by a power supply inside the CDI module. This can be achieved by technology known as DTS-i digital twin spark ignition system which combines strong performance and fuel efficiency. In India Bajaj has patented for dts-i technology. It has become a fashion for the people especially living in urban areas to ride such vehicles. Click here to sign up. Remember me on this computer. Which is typically cast from aluminum or cast-iron before receiving precision machine work.

In a reciprocating engine, it translates reciprocating linear piston motion into rotational motion.

Stroke is defined as the distance traveled by the piston from one of the dead centers to the ln dead centre. Under normal conditions it is desirable to run the engine on the maximum economy mixture, viz. The important attributes of rapid combustion are improved tradeoff dtso efficiency and NOX emissions, greater tolerance towards EGR exhaust gas recirculation or excess air, which can improve vehicle drivability and greater knock resistance, thereby allowing fuel economy with higher compression ratios.

Digital Twin Spark Ignition System: The papr head is equipped with two spark plugs, instead of the usual one. It has become a fashion for the people especially living in urban areas to ride such vehicles.

The exhaust valve closes shortly after the piston reaches T. The reciprocating piston motion is converted into rotary motion of crankshaft by a connecting rod and crank.

The process of mixture preparation is extremely important for spark ignition engines.

So for the instantaneous burning of fuels in I. 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.

The reed switch is connected to dtzi Digital C.

Remember me on this computer. During combustion the chemical energy of fuel is released and there is rise in temperature and pressure of gases.

This can be achieved by technology known as DTS-i digital twin spark ignition system which combines strong performance and fuel efficiency. Hence in a four stroke engine work is obtained only during one stroke out of the four strokes of the piston required to complete one cycle.

This is overcome by the DTS-i by having 2 spark sources on the opposite sides which reduces the flame travel as stated above.

The perfect Combustion in Internal Combustion engine is not possible. The distance between the spark plugs depend dtwi the displacement of the engine. Because the ignition rate is double; the power is generated product and gases expands more faster which in turns push the piston more powerfully and we get better no and because approximately all the fuel being ignited at once we get better fuel efficiency as well. Both the valves are closed and the piston moves from B.

In order to do the conversion between two motions, the crankshaft has “crank throws” or “crankpins”, additional bearing surfaces whose axis is offset from that of the crank, to which the “big ends” of the connecting rods from cylinder attach. The rings make near contact with the cylinder walls sleeved or sleevelessriding on a thin layer of lubricating oil; essential to keep the engine from seizing and necessitating a cylinder wall’s durable surface. The admission of charge inside the engine cylinder continues until the inlet valve closes at B.

The process of mixture preparation is extremely important for spark ignition engines. The charge consists of a mixture of air and petrol prepared by the carburetor. Thus force exerted on the piston would increase leading to better work output.

At the same time use of two spark plug improves thermodynamic efficiency and power available. Cylinder head is casting encloses the combustion end of the cylinder block and houses both the inlet and exhaust poppet- valves and their ports to admit air — fuel mixture and to exhaust the combustion products.

The obvious outcome of this is enbine torque, better fuel efficiency and lower emission. So for the instantaneous burning of stsi in I. The process of mixture preparation is extremely important for spark ignition engines. However very few small capacity engines did eventually implement such a scheme in their production prototypes.
