Diesel is Cleaner After All

Study Finds That Diesel Better for the Environment Than Gasoline
Fri, 07/14/2017 - 2:29pm 6 Comments
by Kenny Walter - Digital Reporter

...
An international team of researchers have discovered that modern diesel cars emit less pollution than gasoline-based cars, which could result in regulators shifting their focus to gasoline-powered cars and other sources of air pollution.

“Diesel has a bad reputation because you can see the pollution but it's actually the invisible pollution that comes from gasoline in cars that's worse,” Université de Montréal scientist Patrick Hayes said in a statement. “The next step should be to focus on gasoline or removing old diesel vehicles from the road.

“Modern diesel vehicles have adopted new standards and are now very clean, so attention needs to now turn to regulating on-road and off-road gasoline engines more,” he added. “That's really the next target.”

Re: Diesel is Cleaner After All


Just what I have always been saying.
The EPA is deliberately being unfair to diesels because US car makers don't know how to make a small diesel. But diesels are obviously superior in terms of being cleaner and emitting less harmful emissions.
That is obvious since VW diesels sold in the US were getting 56 mpg, and in the rest of the world they are getting over 200 mpg.

If you want more proof the EPA is counterproductive, just look at the gasoline Smart car. In Europe it gets 86 mpg, and in the US it only gets 34 mpg.

really? name one normal production car that ACTUALLY (in normal useage) gets more than 80 miles to the US gallon.

Sure with specialist cars with very finely tuned engines ultra skinny high pressure tires, no alternator you MIGHT get 200 mpg but that isnt really a production car is it?

there is often a vast difference between what a manufacturer will claim and what Herbert Q Higgingbottom will actually be able to achieve In the UK (with its 25% bigger gallon remember) smart cars are 'supposed' to get 68mpg although whether or no any one actually does I dont know (but I doubt it)

My family have pretty much driven diesel cars exclusively (apart from my son) for about 20 years we have owned several VW diesels none of which bettered 60mpg in normal usage and our current Honda CRV struggles to better 40 mpg (and again we have a 25% bigger gallon than the US) my daughter's VW 3cyl 1.4liter turbo diesel is claimed to do 72mpg in reality it does about 60 although if you are prepared to sit on the inside lane of a motorway at 45mph Im sure that that would rise (unlike our CRV which does 39 -40 however you drive it)

I agree on the exaggeration there are NO 200mpg engine driven cars for real use. The truth that diesel exhaust can be visual does not mean it is dirtier as noted it tends to actually be LESS unhealthy yet still unhealthy.

For the US and especially CARB to mandate emissions controls that decrease fuel mileage while as a result increasing consumption for each additional device is stupid. For a miniscule removal of release agent they exponentially increase consumption leading to volumes of increased releases regardless if 'cleaner' it is VOLUMES more released.

I enjoy diesel engines for my farm and my truck, the "Advances" in fuel chemistry not only decreased my fuel mileage by 25% it as cost us far more then direct expense of purchase by leading to internal engine/fuel system damage to the older units. So called 'Benefits' are outweighed by the damage presented.

No, the imperial gallon is never used in the calculations.

Here is a limited production VW that gets 261 mpg.
http://www.greencarreports.com/news/1087980_orders-for-261-mpg-volkswagen-xl1-exceed-production-of-200
But it is expensive.

{...
Orders For 261-MPG Volkswagen XL1 Exceed Production of 200

Volkswagen's XL1 might be one of the most exciting and unusual green vehicles of recent years, but it's certainly not one of the most accessible.
Pricing around the $150,000 mark, based on the German price of 111,000 Euros, puts it in the same league as high-end sports cars. But as we've come to expect with the rare and the bespoke, there'll always be someone out there who doesn't mind paying for something exclusive.

It comes as no surprise that demand is outstripping supply for the sleek 261 mpg XL1. According to Inautonews, VW has more customers for the car than its 200-unit production run can accommodate.

In an unofficial statement, Volkswagen told the site, "Since we have many more interested customers than vehicles, we will have a selection process. At the moment we cannot give any more information on this process." That's going to leave a lot of disappointed customers in the XL1's aerodynamic wake...

A two-seat, low-slung diesel plug-in hybrid, the XL1 marks the culmination of years of ultra-efficient concept vehicles from VW, beginning with 2002's "1-liter car". The 1L was a pet project of then-chairman Dr. Ferdinand Piech, and over the years the car transformed into the VW L1 concept and the VW Up! Lite.

The XL1 was finally confirmed for production in February this year and was launched at the 2013 Geneva Motor Show.

The production car uses an 0.8-liter, twin-cylinder turbocharged diesel engine, paired with an electric motor.

But it is easy to get 100 mpg.
Here is a do it yourself example from "Mother Earth News".
http://www.motherearthnews.com/green-transportation/green-vehicles/build-your-own-car-zm0z13amzmar

Here is a production car no longer built.
{...
How many miles per gallon does your car get? 34? 35?

If you ask Jerry Bartlett, the answer would be 200–and not in a Pruis.

“As far as I know there are only three of these vehicles in existence,” Bartlett said.

The car is a modified Urba Centurion originally designed by Robert Q. Riley–one of only three in existence; the Lane Motor Museum in Nashville, Tennessee displays one and the other was used in the 1990 movie Total Recall starring Arnold Schwarzenegger (in fact, the original wheels used on the Total Recall car are on Bartlett’s Centurion).

Bartlett, a computer technician at SUNY Canton (a New York college just south of the Canadian border) was inspired to build the car by a February 1982 copy of Popular Mechanics, then Mechanix Illustrated, which now hangs on the wall above his desk at the college.

The Centurion is built on a 1966 Triumph Spitfire frame with a custom body made with fiberglass over foam and runs on a three-cylinder Kubota diesel engine. Its top speed: 65 mph.

On April 11, 2014, the Centurion tied for the Most Fuel-Efficient Vehicle award in the Toyota Green Grand Prix Doris Bovee Memorial Road Rally at Watkins Glen International racetrack.

Here is 150 mpg.

{...
German startup Loremo AG will debut its concept car at the Geneva Motor Show this week. "Loremo" is derived from "low resistance mobile," and embodies the company's philosophy of efficient transportation that consumes minimal resources during both production and operation. In practice, this means lightweight, aerodynamic vehicles with phenomenal fuel efficiency.

The Loremo will be offered in two models, the LS and GT. The LS is powered by a 20 hp, 2-cylinder turbodiesel, while the GT gets a 50 hp, 3-cylinder unit. Both are 2 2, mid-engine/RWD configurations with a 5-speed gearbox. The GT will go from 0-62 mph in 9 seconds, but the real strength of the Loremo is fuel efficiency - the GT consumes only 2.7 liters per 100 km, while the LS needs only 1.5 liters/100 km. According to my calculator, the LS will go over 150 miles on a gallon of diesel! More after the jump.

Light weight and low drag are the watchwords for Loremo - the LS weighs only 990 lb, with a Cd of 0.2.

According to Loremo, the LS will be priced at about $13,100, while the GT will sell for less than $18,000.

Not just or STRICTLY diesel, but a Diesel Electric Hybrid. The engine does not actually ever drive the machine but recharges the storage cell to power an electric motive motor.

Still a plug in after use and still draws grid power to fully recharge.

True it does have an electric motor and batteries as well, but what about the other 3 after that, which get 200, 100, and 150 mpg and only use internal combustion, no electric motors?

Ultralight weight, two passenger, one 20hp the other 50hp given to that low power to weight as well low weight and aerodynamics, only good for open road short term travel. In-city aerodynamics plays "0" percentage, on the road lack of capability rules out family use or travel use for anyone with compound baggage.

My 1971 VW Beetle made 38-44 mpg on good days when I paid attention to speed limits had little load inside the machine and fair winds assisted.

All true.
But, take your 1971 beetle and reduce the weight intended for off road use, make it even lighter with carbon fiber and fiber glass, add computerized ignition and fuel injection, increase the compression, add exact overhead camshaft timing, etc., and it likely could easily have gotten twice the mileage.
Things like turbo charging can add the hp of a larger engine without adding weight or reducing mileage if you do not hit the gas hard enough to make it spool up.
We have had over 40 years to be able to do better, and still have not.
Instead we are just making cars even heavier, with even worse mileage. Blunt, steel, large engines, etc.
