Diesel vs Petrol

I gonna write about BMW once again. Today on the road I saw a BMW 530d. During then I was wondering why does people buy a 530d instead of a 530i. I always think that fuel efficiency for petrol is always better compare to diesel. Probably because all heavy duty vehicle back home uses diesel and it emits lots of carbon monoxide to the air. When I saw BMW 530d on the road , I was thinking that there are something on 530d that I will need to find out. First thing that i found out about 530d is the fuel consumption. It is more efficient compare to 530i. The next thing will be the huge torque advantage (369lb ft vs 221 lb ft) over 530i. I manage to find an article that wrote about the advantage of diesel over petrol and the technology used in making the fuel consumption more efficient.

As little as fifteen years ago, the diesel/petrol conundrum didn’t really exist. Diesels were slow, unrefined and fit only for taxis. It didn’t matter that they were cheaper to run than the petrol equivalent, because to stop at the black pump was to become a social pariah. But in the past few years, new technology has revolutionised the diesel engine so that they’re now a genuine and desirable alternative to petrol power.

The most significant technological breakthroughs concern the development of direct injection and common rail turbodiesel technology. Direct injection, as the name suggests, is a process by which the fuel is injected directly into the combustion chamber. The fuel supply can therefore be controlled more precisely, improving the efficiency of the combustion process. The latest common rail systems can also operate at a much higher pressure, further enhancing the detonation process. The result is more performance with improved fuel efficiency.

No less important has been the development of pre- or ‘pilot’ ignition systems. A tiny quantity of fuel is injected into the chamber and ignited before the primary combustion takes place. This minimises the harsh “knocking” or rattle sound traditionally associated with diesel powerplants. As a result, the latest diesel engines are now all-but as refined as their petrol equivalents.

The traditional image of diesel has been utterly transformed and it hasn’t taken drivers long to catch on. Executives who once sneered at the thought of a diesel car, are now revelling in the performance, refinement and fuel economy of the latest six and eight cylinder turbodiesel engines.

The petrol-powered BMW 530i and the diesel 530d cost similar money. The 530i has more power (258bhp vs 218bhp) but the diesel has a huge torque advantage (369lb ft vs 221 lb ft). In real world driving conditions, it’s the 535d that’s the faster, more engaging companion. And that’s before you consider the fuel savings – the 530d achieves an average of 40.9mpg, 8.8mpg more than the 530i. The diesel 5-series is not just more enjoyable to drive; it’s also cheaper to run.

This diesel-mania is even infesting the racing community. We’ve had diesel racers before – VW even sent a diesel van to the track – but they were no more than a token gesture, a marketing gimmick to appease the do-gooders. But now Peugeot is committed to building a diesel-powered Le Mans racer and Audi might well follow suit. They reckon they can achieve performance and economy, which in a 24 hours race is crucial.

Some commentators have suggested that we’re entering the age of the diesel, but such proclamations might be premature. Much of the technology that’s being used to such fine effect in modern turbodiesels is also beginning to filter into petrol engines. The Volkswagen group, for example, already offers a range of direct injection petrol engines that offer improved fuel economy and lower exhaust emissions. Audi’s Le Mans winning R8 was powered by a direct injection petrol engine, and a road-going derivative is employed to fine effect in the Volkswagen Golf GTi.

Sports car manufacturers will continue to favour petrol over diesel power. Petrol engines tend to weigh less than the diesel equivalent – an important consideration in a high performance car – and their free revving nature makes them more fun to drive. Many sports car drivers also continue to prefer the sonorous roar of a performance petrol engine to the more muted, deep bass mutterings of a diesel. Don’t expect to see a diesel-engined Ferrari rumbling down your high street anytime soon.

And while Le Mans may soon be populated by diesels, sprint racing will continue to be dominated by petrol power. A diesel-powered F1 car remains a preposterous suggestion, unless they change the rules. The point is not that diesel is about to replace petrol, but that for the first time we have a genuine choice. That can only be a good thing.

Dinner at Davids

Havent been making personal post for quite a while. Probably because my life is too boring to post anything up. If you asked me what I have been doing ? Has been doing reading most of the time. Hunting for information that I need. I would like to make the blog more informative rather then just on my daily life. I would have to agree that most of us had enter a different stage of life. Last time when we were in uni we used to talk about uni and muiss. Now there is no one time that we didnt talk about work or property. I guess the next stage of our life, we will be talking about marriage and kids. I am no where near there yet. =P Went to Davids Restaurant for dinner. First time trying out this place and the food wasnt too bad. Proportion of the food was quite huge. The food there is something different compare to what we usually have for dinner.

Still waiting for a reply from my friend whom I suppose to meet. Send her two sms she still yet to reply me. I wonder if tomorrow lunch is still onz.

Evolution of my life in Technology World

I started on registering my own domain at the age of 16. My first domain was mp3planet.ws. During then p2p is yet to be popular and many people download songs off from the website. Webhosting is so expensive during then. I was paying around US14/month. When p2p is around, mp3 website started to lost its popularity. Songs is accessible in a easier manner. Maintaining a large song database is not an easy task. New songs comes out every single day and putting new songs in the website is just too much of work. But during then online advertisement brings great benefit to website. There is company that pays US0.20 for a click on the bannner. Security wasnt that tight and you can practically asked people or friends to click on the banner to put money into your pocket. As I was using dialup during then, IP address for every single click will be different. If you apply to be a online affiliate from the advertising company, you should be familiar with linkshare, befree and CJ during then. There is 101 ways people tried to cheat money out of these advert company. One of the software use was cheatzrus which was created by one of the smart ass people. The software was created using mIRC script. People who knew about the software will join this channel and as all of us have an unique ip address, it will make in such way that people in the channel will goes through the advertising link that you put up. This process is automated where people does not need to be physically clicking on the link. After a while all these advertising company knew about it and they strengthen their security system. That was when the cheatzrus era ended.

The next domain i had was techcommunity.us. Installed xoops script on the server. I was quite fascinated with the script. So I decided to just had a webserver and play around with the script. It is an online community script where you can install different kinda of plugin to suit your needs. After that, there is when I had winson-talk.net when bloging is popular. Some people sets up their own private blog on a paid hosting. So I decided to have a try and see as private blog provides greater flexibility on the things you can do to your blog. As for my personal blog, I changed from xanga to personal blog to blogspot to personal blog to wordpress. I did not keep some of the archieve that I have for my blog. Some of the experience that I posted, I did not want to bring it over to my new blog. As my life is always interesting and I went through different sort of experience and some of the interesting experience I would prefer to leave it behind. Blogspot I deleted it totally as that was the worse part of life I have been through. I stop blogging for 3 months before I started on wordpress and only lately people knew about the existence of winsonlee.wordpress.com. After trying to play around with the blog only I realise that wordpress does not give me the flexibility to do things that i want.

What are the things that I found out that I couldn’t do in wordpress ?

1) I can only choose template that is being defined in the list.

2) I cant change css code for the template. WordPress requires me to pay in order for me to change the css script.

3) I cant put an external hits tracker.

4) I cant put a chatbox.

5) The post box is far too small then what i want it to be. I have data up in the post and I need to refer to it in order for me to write about it. Instead now I ended up using notepad and writing my blog referring to the data I paste it on the notepad.

6) Last but not least, I cant put google map in frekin word press. There are place that i would like to refer to using google map.

That is when I thought of putting my blog onto a private server again. I have been hunting for one ever since last week. Finding a hosting server is easy. But finding for a good hosting company that provides good support and has all the features that I want is hell difficult. Sad to know that winson-talk.net domain is taken. Else I would want that domain again. Currently they only have winson-talk.com. Somehow I just dont like .com. But if that is my only choice I would just grab it instead. Next entry I will post up the detail of the hosting company that I found and the deals that I got with them.

Did I mention that porn website was one of the project that I have created ? I have never told anyone about this before as this topic is quite sensitive. Till now I cant believe that I did that. I have created it but ended up I decided not to get it onto the web. During then I was only form 5.  If you do realize  porn industry in the web has the largest market share and porn advertising company can pay you few times more then the normal company.  During then I was thinking but of course it did not comes to my mind to know what is right or wrong.

During my previous post I wrote about the median growth rate at major city like Melbourne, Perth, Sydney and Perth. Today I was looking at HeraldSun and they wrote about the median growth rate for individual suburb. I was suprise to see that there are 7 suburbs that growth rate is more then 50%. Blackburn achieve growth rate of 63.7% for the year of 2007.
