This is employed to keep the wind screen clean for good visibility during rain or snowfall etc. Wind screen wipers are operated electrically by means of a small motor but some vehicles are fitted with compressed air for this purpose. The electrically operated wind screen wiper is shown in Figure. The motor drives the worm A which rotates the wheel B. The toothed sector and connected to the wheel B with the help of link is D. When the wheel B rotates, Sector E reciprocates about the fulcrum G. This motion is then imparted to a similar sector F which fitted the wiper arm on the spindle mounted. Wiper blade is attached to the wiper arm by means of a spring lock. The wiper blade holds the rubber wiping element. The wiper arm pivots over the wind screen under spring pressure and ensures adequate and wiper blade pressure against the wind shield glass. Whenever the replacement of blade or cleaning of wind shield glass is required underneath the wiper blade can be lifted from the glass ​​wind

FOUNDER: - SOICHIRO HONDA ESTABLISHED AT: - HAMAMATSU ( JAPAN ) ON 24 TH SEP. 1948 He dreamt of providing people, everywhere in the world an economical means of transportation. He invented better ways of making piston rings and found a company around the idea and began production. Then his company started producing small motorcycles, including one built in 1949 called D-type dream.   Then he thought of high capacity motorcycles and taking them to racing. So his company made bigger and faster machines, two, four, five and six-cylinder race bikes and participated in the Isle of Man TT race (125 cc motorcycle class). He wanted to share his new motorcycles with the world and therefore he opened American Honda Motor Co. in Los Angeles . Also Honda began manufacturing motorcycles at its Suzuka factory in 1960. Honda launched its first sports car, the S500 in Japan and entered Formula-1 in 1964. In 1989, Soichiro Honda became the first Asian to be inducted into U.S. Automotive Hall of Fam

Automotive air conditioning is done to control the temperature, humidity, purity of the atmospheric of the air and circulate the same in the automobile to make the journey of passengers comfortable so that they Should not feel too much cold in winter and too hot in summers. Earliest, most of cars were having the cooling provision only as shown in Figure. It consists of refrigeration system, an air circulation and distribution system and a control system as shown in the layout. It includes the compressor, condensor, dehydrator and connecting lines in addition to expansion valve, orifice tube, suction throttle valve and high pressure cut off  switch. The commonly used refrigerant is freon 12 . The compressor driven by a belt from the engine pulley through an electromagnetic clutch sucks the low temperature and low pressure refrigerant vapour from the evaporator ad compresses it to high temperature and high pressure vapor. Then it is discharged to the condenser Air is caused to flow acros

This clutch is similar to the centrifugal clutch with only difference that light clutch pressure springs exerting low pressure at idling speeds are used. The pressure between the plates is Increased with Increase in the speed of rotation of the clutch in Proportion to the pressure requirements by means of centrifugal weights linked to the pressure plate Figure shows the action of the rotating weights which trend to move the pressure plate towards the flywheel and the ends of the release levers are moved back against the throw bearing. Relatively light clutch pressure springs exerting low pressure at the idling speed is enable depression of the clutch pedal for shifting of gear.
