Petrol Car VS Diesel Car

Petrol Car VS Diesel Car

The Similarity

The diesel and petrol engines that are used in most cars are highly similar. In essence, they are internal combustion engines that usually works using a 4-strokes cycle. In an internal combustion engine, the power cycle is made up of four phases: intake, compression, power and exhaust; thus it is called the 4-strokes cycle

1st Stroke: Intake Phase

During the intake phase, air is drawn into cylinder through the opening intake valve. This is cause by the vacuum that was created when the piston is drawn downwards.

2nd Stroke: Compression Phase

Next is the compression phase. During this phase, intake valve closes and the piston is drawn up, compressing the air with fuel.

3rd Stroke: Power Phase

At this point, the compressed mixture of fuel and air is ignited to cause an explosion. It is this explosion that causes the piston to be pushed downwards and drive the crankshaft to produce motion.

4th Stroke: Exhaust Phase

During this final phase, the exhaust valve will be opened and when the piston is being drawn up, it pushes the spent air-fuel mixture out of the cylinder through the exhaust valve, allowing a new cycle to begin.

The Differences

The main difference between diesel and petrol engines is that petrol engines usually use spark plugs to ignite the air-fuel mixture, while diesel engines rely solely on heavily compressed air. The temperature of the compressed air could be made to increase high enough to ignite the diesel fuel if the air is being compressed heavily enough.

Diesel Engine


Diesel is also considerably cheaper than petrol. However, this comes with a drawback. Diesel engines emit more noxious gases and CO2 per litre of fuel used than petrol-powered cars. Diesel engines also require more raw materials and money to manufacture as well.

This October help save the environment from the noxious fumes of diesel and save your wallet from the cost of the petrol. Book one of our selected cars and you can receive a $10 petrol voucher for every 2 days of bookings.

4 Fun Facts About Singapore's Weather. Number 4 Will Blow Your Mind!

Over the last 2 weeks, we have seen some rather extreme weathers in Singapore. But are they really that extreme? Here are some fun fact about the climate of Singapore.

1) Rainfall

On 8th Jan, 9 different locations in eastern Singapore experienced one of the most intense flash flood in recent history. The flooding are due to a heavy rain that poured 118.8mm of rain in just 4 hours. That's about 2 weeks worth of rainfall in just a couple of hours. But did you know, back in 2nd Nov 1995, a record breaking 147mm of rainfall fell in just 1 hour. So before you complaint about how heavy the rain is, remember that it can always be worse.

On the opposite end of the spectrum, Singapore had experience some really dry months as well. As recently as Nov 2014, the total rainfall in Singapore for the month was just 0.08mm. A farcry as compared to what we had been experiencing for the last 2 weeks

2) Temperature

Singapore has been bless with nice, cooling weather for the last 2 weeks. One of the night, the weather dropped all the way to 21.9 degree Celsius. This is the lowest temperature that Singapore has ever experience since 1934. During the night of 30th Jan 1934, the temperature in Singapore was at 19.4 degree Celsius.

3) Uncommon weather

Singapore is no stranger to unusual weather as well. Back in 2013 and 2008, Singapore was hit by a sudden hail. Irregular lumps of ice starting falling from the sky in 5-minute burst.

4) Wind

Strong winds can have some really devastating effects. While Singapore don't suffered from extremely strong wind such as those from the recent Hurricane Irma and Hurricane Harvey. We do have our own share of strong winds. Back in 2010, a gust of wind in Singapore was recorded to be at 90.7km/h, that is faster than the speed limit of our expressway.
