Car Tune-up Tips

Published by:

Before the emergence of electronic systems in cars, a tune-up would normally include repairs of the ignition, engine controls, and fuel injection, which are nowadays undertaken by electronic adjustments.

A modern car tune-up should include processes of preventive maintenance, analysis of performance and minor adjustments, which might be causing driving problems. If conducted properly, a car tune-up usually helps in making the drive smoother, increasing mileage, and preventing any minor problems and symptoms such as poor fuel economy, low power, stalling engine, and ignition problems of the vehicle from getting serious.

Complete Car Tune-Up Checklist

The tune-up of a car can be broadly classified into minor, moderate, and major types, which can include one or more of the following procedures.
Checking the operation of safety accessories such as lights, wipers, tires, indicators, horn, etc.
Replacing the spark plugs and rotors.
Checking all belts and hoses for wear and tear.
Checking, adjusting, or replacing the distribution cap and ignition timing mechanism of the engine.
Checking the levels of engine oil, coolant, brake fluid, and transmission and power steering fluid.
Checking the wires and performance of the ignition unit, and replacing it if needed.

Mechanical Fuel Pump

Heard that you are a regular and a very faithful user of your car?! Time and again the need for you to use your four wheeler occurs, right? Perhaps, you must be maintaining it very well! Many, just like you, are very particular to adapt to preventive measures for maintaining their vehicle. Well, that’s good news as they would never be betrayed by their vehicle in the middle of nowhere! But not all people are so priggish to give their vehicle for maintenance every few months. Such ignorance and carelessness basically leads to several car problems, one of which is a mechanical fuel pump problem.

Although this is the most unexpected and uncommon problem from all the expected ones, it seems that you cannot turn a blind eye since your vehicle has faced one. So the fact is to troubleshoot the problem and repair it at the earliest. How? Look further below, but before that let’s have a brief discussion on the entire working of the mechanical pump in a vehicle.

Compression Ratio

Published by:

Compression is squeezing something so that it occupies a smaller volume. Ratio is the proportion between two quantities or numerical values. The basic unit of an engine assembly is a combustion chamber and piston combination. This ratio is a proportion which denotes the degree of compression achieved, in an internal or external combustion engine, when the driving pistons compress the air-fuel mixture in every engine stroke. It is a ratio of air-fuel mixture volume, when a piston is at the end of its up-stroke, to the air-fuel mixture volume at the end of its down stroke, in a combustion chamber. It is a measure of the air-fuel mixture compression and density achieved, in every engine stroke.

The combustion chamber is a cylinder, which is fed with a mixture of air and vaporized combustion fuel. A piston is placed inside the combustion chamber and it makes up and down movements, according to pressure applied. The air-fuel mixture, fed inside the combustion chamber, is ignited, when you turn on the ignition of the car.

The explosive combustion makes the piston move up and every time it comes down, it compresses the air-fuel mixture again, igniting it in the process.

Motorcycles Automatic Transmission

Generally, you will observe that most people who want to learn how to ride a motorbike mainly worry about the gear changing task. If you are one of them, auto-transmission can solve your problem. As the name suggests, these are motorbikes that do not include the standard gear transmission setup that also involves a clutch. These non-geared motorbikes are the best choice for people who want to learn how to ride, or even for those who do not want to worry about changing gears while riding.

Honda DN-01
The Honda DN-01 is a cruiser manufactured by Honda that was made available for commercial use in 2009. This is one of the best auto-transmission motorbikes available in the market to be ridden on roads. It has a liquid-cooled 680 cc V-twin 8 valve engine, with a 43.3 bhp. It reaches a speed of 60 mph in 7.4 seconds and tops the speed at 113.1 mph. It is fitted with the revolutionary Continuously Variable Transmission (CVT) which is referred to by the manufacturers as “Human Friendly Transmission”. The latest price reported is around USD 15,600. With a total fuel capacity of 4.0 gallons, it gives about 42.3 mpg.
