Electric Power Steering VS Hydraulic Power Steering

Its been a long time I have been thinking to write this article about the two most commonly used power steering technologies, viz. Electric Power Steering and Hydraulic Power Steering. Before i tell you the difference, lets talk a few words on the basics.

What is power steering?

Power steering is a system which helps to steer the wheels with some source of power other than the drivers manual force with which he turns the steering. This feature adds to the comfort while driving as less effort is needed to turn the steering by the driver. Power Steering is specially important for the cars which have engine in front and there is a lot of weight on the front wheels.

For rear engine cars like Tata Nano or light weight cars like Maruti 800, its ok to have no power steering and still drive comfortably because of low weight on the front wheels. But for heavy cars and also as a luxury feature power steering provides lots of ease.

Hydraulic Power Steering

Hydraulic power steering uses high pressure fluids for assisting the steering movement. It uses a plunger type arrangement for its working. When the driver turns the steering wheel, it opens up the flow or pressurized fluid in such a way that helps to turns the wheels in the required direction.

Electric Power Steering

Electric power steering works with the help of an Electric Motor and a control unit which has some sensors. The motor runs on battery and will use electric power to assist the movement of steering when the driver turns the wheel.

Combi-brake means that the brake will act on front and rear wheel together every time you apply the brakes. This means a lot of improved safety.

MPFI Technology In Plain English

I was commuting with my friends back from office one evening when one of them asked me

What is an MPFI Engine?

You must have seen cars with specifications which mention words like MPFI and CRDI or CRDE. To an automotive engineer or enthusiast, it means something, but for a common man, it may not make much sense.

MPFI Engine

In this article I will talk about MPFI in simple English so that a person who is not an automobile engineer can also make sense of it.

MPFI means – Multi-point Fuel-Injection (also called fuel-injection system)

The term MPFI is used to specify a technology used in Gasoline/petrol Engines. For Diesel Engines, there is a similar technology called CRDI. We will discuss CRDI in a separate article to avoid confusion.

MPFI System is a system which uses a small computer (yes, a small computer without keyboard or mouse, its more like a microchip) to control the Car’s Engine. A Petrol car’s engine usually has three or more cylinders or fuel burning zones. So in case of an MPFI engine, there is one fuel –injector installed near each cylinder, that is why they call it Multi-point (more than one points) Fuel Injection.

Cars In Year 2020 - Future Of Car Technologies

I am no astrologer but an Engineer with a vision and innovative thoughts. When I look at the cars around me I realize how much these car have evolved in last 10 years. The changes are huge and drastic considering technological advances. But bigger changes are yet to come, or should I say the changes are coming faster than ever before.

I keep reading and thinking about the technologies, and I also have several ideas in my mind that i would like to have in cars. In this article I will try to list the technologies which I feel will be really common in cars of future.

Alternative Sources Of Energy :

First and foremost, I don’t see the conventional petrol or gasoline or diesel going a long way into future. The fuel prices are bound to shoot with time and depletion of crude oil from planet would make things worse. I feel the next big thing will be electrically driven cars or maybe hybrid cars which have electrical as well as conventional fuel burning engines. But electrical cars have better future prospects because they are technically simpler than combustion based engines. One of the most beautiful example of this is Michelin – E – Wheel technology. Source and picture credit : Engadget. This technology basically removed the need of an engine by putting the motor that drives the wheels right inside the wheels. These kind of innovations not only make cars cheap, but also light weight, more reliable, and easy to produce. We are seeing an era of Hybrid cars that run on petrol and battery, tomorrow we will have more cars that run primarily on batteries. Also fuel cells are a great opportunity if they can be produced for cheap cost. More than anything, pollution, cost and economy will decide what fuels we settle for, but crude is meant to go in a few decades anyways.

12 Easy Tips To Increase Your Car Mileage

In the days ever rising fuel prices, the fuel bills are digging deep into the pockets of a common man. I’m going to share some practices which can get you more miles out of your fuel by increasing the fuel average or fuel mileage of your car.

Phone001 

Tip 1: Do not accelerate too fast

Too quick acceleration consumes too much fuel, accelerate slowly and gradually. That will save quite a significant amount of fuel in city driving.

Tip 2: Do not use clutch too much

If you use a manual transmission car, as is mostly used by people in India, do-not drive with clutch pressed, or use clutch only when needed, too much use of clutch will waste a lot of fuel.

Tip 3: Change gears appropriately

This is also applicable for manual transmission cars. Use correct gears at correct speeds, this will help save the fuel. For correct speeds, see your car’s user manual.

Tip 4: No Excuses to delay car service

Get the car serviced as per manufacturer’s recommended schedule. This will ensure good health of engine, less maintenance due to break-down.

Tip 5: Do you drive in dusty environment? Clean the Air-filter

If you drive in dusty environment the air-filter gets filled with dust and makes the engine suffocated. Clean the air-filter more often than the service schedule( say  every 5000 KM or so) , this will help the engine run more easy and consume less fuel. Trust me, its going to really help.

I Spray Painted On My Car Scratches !

I did the spray paint touch-up myself on my car using a paint kit that I ordered online. The results are fine, not too good, not bad either. In this post I will share with you how I did it, and the results.

I felt really disturbed when my sister mistakenly scratched the left side front door against a wall. It was so badly scratched that even after getting a rubbing treatment some scratches were visible.

I asked the showroom guys, they gave me an estimate of Rs. 3000 for the job. I asked the local denting-painting guy, he asked for Rs. 1500 for the same. I decided to leave it like that only.

But one fine day I came across a web-site (www.com-paint.com) that sells car spray paints of the perfect colors based on various car brands. Each paint kit costs Rs. 300 for metallic colors and Rs. 260 for non-metallic color. So I ordered one kit for my Hyundai i10 of Champagne Gold color (metallic). In that kit, you get one paint spray can and one can of Finishing Solvent. There is a video on the web-site which tells you how to do the paint job over the scratch.

Now I will tell you how I did it and the pictures of the car after the paint was done. Read on.
