POWER STEERING

POWER STEERING:

Power steering assists the driver of an automobile in steering by directing a portion of the vehicle’s power to traverse the axis of one or more of the road wheels. As vehicles have become heavier and switched to front wheel drive, particularly using negative offset geometry, along with increases in tire width and diameter, the effort needed to turn the steering wheel manually has increased often to the point where major physical exertion is required. To alleviate this, auto makers have developed power steering systems: or more correctly power-assisted steering on road going vehicles there has to be a mechanical linkage as a fail safe. There are two types of power steering systems hydraulic and electric/electronic.

What is DTSI Technology & DTS-Si Technology ?

What is DTSI Technology & DTS-Si Technology ?

In DTSi, instead of 1 we are using 2 spark plugs. Flame front formed is able to consume more air-fuel mixture as compared with 1 spark plug, thus more complete burning and more efficiency.

In DTS-Si, with addition of 2nd spark plug, what they are doing is relocating valves position. With proper designing of inlet and outlet valves you can induce extra swirl for inoming air fuel mixture. Due to turbulence, extra efforts are provided for proper mixing of air and fuel. (We can not allow petrol to go in liquid droplet form, it should be finely atomized). With well atomized air fuel mixture, efficiency increases.

Thermoelectrically operated fan using a candle

Thermoelectrically operated fan using a candle.

( Operate a fan with the candle during power cuts/ villages where there is no power!!)

Innovation at its best.
