Introduction
Digital Twin Spark Ignition has two spark plugs that use to ignite the charge in the combustion chamber.
2 spark plugs at either ends of the combustion chamber help in faster and better combustion.
It only use in the petrol engine
Engine Construction
The engine used on the Alfa 164 T. Spark is a four-in-line cylinder unit whose weight has been considerably reduced with all aluminum-alloy engine block, cylinder head, oil sump and tappet covers.
Eight counterweights ensure optimal balancing of the high strength nitride steel crankshaft.
The pressed-in cast iron cylinder liners feature wet mounting for more effective heat dissipation
Cylinder capacity amounts to 1,962 cc thanks to an 84 mm bore and 88.5 mm stroke with the Compression ratio 10: 1. Maximum power output at 5,800 rpm is a remarkable 148 BHP DIN, while maximum torque, of 19 mkg DIN, is reached at 4,000 rpm. The shape of the torque curve has been perfected to make available fully 16 mkg when revving speed reaches 2,000 rpm and 18 mkg as early as 3,000 rpm, thus making the engine's performance much more responsive.
Working of DTS-I system
When the rich mixture of air and fuel enter in the combustion chamber , the two spark plugs
fixed at opposite end of engine cylinder generated spark and this spark burn the mixture that burned mixture gives power to the 4-stroke engine. Here spark generated by the microchip
There are some advance technology used in DTS-i engine which makes it more powerful than the conventional single sparkplug 4-stroke engine like 1. Trics III technology (Throttle Responsive Ignition control System 3rd generation) 2. CDI technology (capacitor discharge ignition)
DTS-SI technology
DTS-Si stands for digital twin spark - swirl ignition, it is similar to DTS-i technology difference being the cylinder has grooves which causes turbulence of the air fuel mixture entering the cylinder making it 'swirl' hence better combustion takes place, giving better efficiency and power
TRICS III
Throttle Responsive Ignition Control System 3rd generation. It is a means of controlling the Ignition by operating the Throttle.
Based on a particular amount of Throttle opening, the Magnetic field generated by the Magnet ,Which opens or closes the switch .
The switch is connected to the Digital CDI, which signals the CDI to change the desired Ignition Advance .
