blogentry-133713-0-70125600-1476784750_thumb.jpgReuters has just published a report saying automakers will be reversing the recent downsizing trends for both petrol and diesels engines as the small engines have trouble passing real-world emissions test.

 

While the turbocharged small engine capacity provided decent power for everyday driving, it is said that small petrol engines 'spew fine particles and carbon monoxide' and that the heat generated by small turbodiesels result in NOx readings over 15 times the legal limit. Renault's 0.9-litre engine was found to inject excess fuel in an effort to stop overheating which would leading to high emissions 'of unburned hydrocarbons, fine particles and carbon monoxide'.

 

Brands which are going towards the 'upsizing' route include Volkswagen, Renault and General Motors. Analysts say that moving forward, strict new emissions tests will kill petrol engines below 1.2-litre and diesels that displace less than 1.5-litre.

Great news.

 

Actually what is the real news here. It is all about profit. Just how many sub 1litre cars a manufacturer needs to sell to make a decent profit compared to a 4 litre car.

 

It is unbelievable that manufacturers are unable to reduce the emissions from small cars. The industry needs spurs on their backside like have another Elon Musk to shake up their complacency.

 

Conspiracy theory suggests auto industry and oil companies are in it up to their eye balls.

 

The bottom line is if each sub litre car can bring in a profit of 50% or more for the manufacturer, I am sure many may just abandon building cars of larger capacities.

wouldnt the drive for variable compression ratio for engine coupled with variable vane turbo the way forward?

A heavily boosted 1.0L engine can replace a lot of the engines out there. Plus there are a lot of savings on weight with such a small capacity engine. I think it's just an excuse and that they are delaying what's coming.

The current TC 1.4L-1.6L engines have not reach its peak. Abandoning them for the TC 1.0L is actually a lot of hard work down the drain.

Actually its about time they do so.

 

Tiny force fed engines may look powerful on paper, but when you use it and compare it back to back with a bigger NA engine of equivlant power o/p, there is still a marked difference in overall driving experience.

 

Tiny engines power delivery tends to be hills and valley... meaning you get big power at some rpm and then power drop off as u rev high and it come back again at even higher revs... this is even more apparant when the car is under heavy load.

 

Also, these tiny engines tends to sound like a high speed industrial sewing machine... unglam sounds

  • A sole-ful tribute

    Car enthusiasts are an emotional bunch. So, I naturally develop feelings for things on wheels, be it four wheels or two. However, I was surprised to discover that I had become attached to my old pair of sneakers, whose soles are so worn that it hurts to wear them.  That is the unequivocal signal to retire them. But I must say "Thank you" before bidding them goodbye. The laceless design is convenient, saving time when you need to rush off in the morning Through thick and

    The best covers are the ones you don't expect

    I'm not a fan of Christmas.  Let's first set aside the unclear and potentially contentious origins of this particular 'holiday', and my general apathy towards religiosity. (Christians celebrate it as the day of Jesus' birth, though some evidence suggests his actual birth was in the spring. Some historians also note that the Christian traditions of Christmas can be traced back to Pagan roots and the Saturnalia festival, and the chosen 25 December date was an attempt by church leaders to appr

    My favourite racing game is back!

    THERE'S A NEW TOKYO XTREME RACER GAME ON THE WAYYYY!!!! This is the best news for fans of this rather understated and obscure racing game. Also known as Shutoko Battle in Japan, this is a series of racing games by Genki, a Japanese game company that was founded in 1990. Tokyo Xtreme Racer 3 is one of the most popular game in the series as it features many cars, opponents and an extensive map For those that have never heard of these games, I'll give you a quick run-down. Inspired by the

    Cleaning is relaxing?

    Every once in awhile, I find myself watching 20-minute long videos on Youtube on something that most people will probably find quite bizarre: Carpet cleaning videos.  (This video has 5.4m views!!!!) It's... a particular kind of Youtube rabbit hole. I concede that.  However, I must say that I find such videos strangely relaxing and soothing. Beyond the ASMR component of it, I do find something quite nice about the specificity and particularity of such videos, and in some
