Car show

I went to a car show in lahore. I went to a car show for the first time. I was so pumped as i love cars, have a look

Four stroke.

Ever wondered that what is men't by four stroke engine? Well i'll tell you. Four stroke is basically the working of the pistons in petrol and diesel engine. I will explain it with petrol engine.

1- Intake stroke.
2- Compression stroke.
3- Power stroke.
4- Exhaust stroke.

* Intake Stroke:
           The cycle starts in intake stroke in which the piston moves outward and petrol air mixture is drawn through an inlet valve into the cylinder from the carburetor.

* Compression Stroke:
               On the compression stroke,the inlet valve is closed and the mixture of air and petrol is compressed by the inward movement of the piston.

* Power Stroke:
                 An electric spark is produced by the sparking plug. On the power stroke a spark fires the mixture causing rapid increase in pressure and temperature. The burning mixture expands and forces the piston to move outwards. This is the only working stroke in the cycle which delivers power to the crankshaft to drive the flywheel.

* Exhaust Stroke:
                  In the exhaust stroke, the outlet valve opens. The residual gases are expelled and the piston moves outward. The cycle then begin again.

Petrol and diesel engine.

Diesel engine named after Rudolf Diesel. In a diesel engine no spark plug is needed. Diesel is sprayed into the cylinder with air. Because the air is at very high temperature immediately after compression, the fuel mixture ignites on contact with the air inside the cylinder and pushes the piston upward. The operation of a diesel engine is quite simple and it's efficiency is greater than that of petrol engine.

Petrol engines require a spark plug to ignite the fuel and air mixture. When fuel is injected in the cylinder through fuel injectors, it is compressed with air by pistons. Then the whole mixture of petrol and air is ignited by a spark plug. A spark plug fires the mixture causing a rapid increase in pressure and temperature. This mixture expands and forces the piston to move outward. Which delivers the power to the crankshaft to drive the flywheel.

Samsung galaxy S9..!!!

The next big thing from samsung is the release of samsung galaxy s9. The samsung galaxy S9 will be revealed on 25 February 2018 at MWC  Barcelona. It will have usual hardware and software updates. Here is a glimpse of S9.

                                                           Could be like this 

Kia Stinger GT

Kia is back in the game with their latest sports saloon. The Stinger GT. The Stinger GT was revealed in 2017 North American International Auto Show. This car is getting famous day by day. The Stinger is well equipped and well manufactured. The Stinger is a good competition for BMW and AUDI. The only drawback in this car is that it's a Kia. But if kia continued making cars like the Stinger GT, they soon will end up in the pack of leaders. It is a RWD (Rear Wheel Drive) sports saloon with a 3.3 L Lambda GDI twin-turbo V6(petrol).

Hennessey F5

The next World fastest car is on it's way. The Hennessey F5. It's name is inspired by the F5 tornado. The fastest Wind storm ever recorded. The Hennessey F5 was first revealed at the SEMA show in Las Vegas on November 1, 2017. The F5 is produced fully in house. The venom F5 is powered by 7.4L Twin-turbocharged V8 engine. It produces 1,600HP and 1,300LBft of torque. The chassis is almost completely made from the legendary CARBON FIBER. The weight stands at 2,950 LB (1,338 KG) with fluids, setting the power-to-weight ratio to 1,196 HP per ton. Hennessey claims that F5 will go from 0-400 MPH in under 20 seconds. Which is faster than the koenigsegg one:1 (0-400 MPH in 36 seconds). Its is currently not listed for sale but is expected to be for sale in 2019. Have a look at this wonderful piece of art.
