Innovation in Cars
1886 is regarded as the birth year of modern car when German inventor Karl Benz patented his Benz Patent-Motorwagen. From Motorwagon to Model T, Budgetti to Porche, Volkswagen to Tesla, cars have improved in speed, performance and efficiency.
The first locomotive what we recognise today as cars was put on road by Bertha Benz, the wife of Karl Benz. In 1888, she coaxed the wheels, topped the oil tank and through the uneven terrain of the village, set out on the world’s first long distance journey of 60 miles. Unfortunately for her, not every thing went well and the automobile broke down. Nevertheless, determined Bertha did not give up and scarified her garter to plug the leaky valve. Then she boarded back on to complete her target course.
Specification of Benz Motor-Wagon
Benz motor wagon weighed less than 100 KGs. It was based on open crank case with drip oiling system and similar carburettor to mix fuel and air. The four stroke engine delivered up to 500 W at 250 rpm and is based on identical four stroke engine that we know today. It reached up to 10mph!
Innovation of Four Stroke Engine
To innovate the automobile industry, it is vital to appreciate the fundamental units that drives the vehicle. Four stroke engine has been implemented to produce required horsepower and was even installed in the above motor-wagon. It is based on the same four strokes that we know today : Intake, Compression, Power and Exhaust. The video below demonstrates the animated representation of four stroke engine operation. Upon leaving the engine, the oil geared with its inertia and weight drives the crankshaft in continuous circular motion. Even Benz Motor Wagon engine was based on the same principles that we know about the four stroke engines.
Two types of four stroke are gasoline and diesel engine. Both have same type strokes but gasoline fuel is ignited by sparks from the spark plug. Modern four cylinder engine would have four time more power compared with Benz Motor Wagon engine and a lot more capable to produce more speed on the road.
Power Drive Train Transmission
In the rear-wheel arrangement, engine sits between rear wheel and coupled with crankshaft to drive the rear-wheels. Crank shaft also controls the clutch and brake system. The transmission drive from crankshaft is fitted with propellor shaft that drives the front wheel arrangement. There is a complex chain of gearing between engine to the connections on the opposite wheels to drive all the four wheels. In front wheel drive, engine sits between the front wheel. For further illustration, see the video here.
Hybrid and Electric Cars
The innovation in cars have led to hybrid and electric cars. This means modern cars are fitted with Electric Motors and rechargeable batteries as opposed to fuel engine to produce horsepower required to drive the automobiles. Electric Motors have been employed to achieve similar crankshaft motion in industrial manufacturing for centuries. As a matter of fact, car manufacturers count on press lines that are driven by large flywheels via crankshaft which are coupled to electric motors.
There is also significant Research and Development currently being carried out to drive all four wheels by separate motors. Such development is possible as the technology to achieve synchronous multi-axis motion control via multiple motors has been used widely within manufacturing industry.
In hybrid versions, both electric motors and fuel engines are fitted in the power train transmission. Mechanical gearing provides smooth swap over between engine and electric modes.
Electric Charging Stations
Modern fuel stations are now being fitted with electric cars charging stations. Technology that is required to charge electric batteries is relatively simple. Accordingly, electric charging stations are now being fitted at homes and parking spaces.
