Man vs. Machine: Vehicle Testing

When testing vehicles for durability and mileage requirements we always come back to the reason we test so thoroughly—the customer.The reason we test, test and test a vehicle is, after all, the end consumer’s safety and enjoyment of the vehicle. Over the past decade we have noticed the pros and cons of testing a vehicle through the use of an dynamometer and other mechanical testing devices versus real-world, real driver testing. Both methods are a great way to evaluate a given vehicle, however, many vehicle testing providers omit the human element.

While mechanized testing, such as a dynamometer, can produce excellent testing and calibration results; it falls short when factors like drivability come into play. While a machine can pump out facts and figures, a human being will tell you whether or not, for instance, the cab is cramped or if there’s a rattle in the dashboard. As with any product, manufacturers strive to keep their target market in mind. In this case, if a vehicle passes durability and mileage tests, but the cab is just uncomfortable or the controls are counter-intuitive, it may hurt the sales of the given vehicle. Real-world, driver testing can help avoid this problem.

CARB Offers New Flexibility Options on California’s Truck and Bus Regulation

The California Air Resources Board recently announced new changes to California’s Truck and Bus Regulation.

Their press release appears below.

ARB unveils proposed changes to California’s Truck and Bus Regulation

Board will offer new flexibility options while still protecting air quality

SACRAMENTO – The California Air Resources Board today unveiled proposed amendments to its Truck and Bus Regulation. The amendments are designed to provide new flexibility to truckers working to clean up their aging diesel fleets while still protecting the important emission benefits the regulation provides. Board members will consider the changes at the April 24 hearing.

The proposed changes were developed after some stakeholders voiced concerns regarding their ability to comply with the regulation at the October 2013 Board hearing. Truckers were able to expand on these concerns at five ARB-sponsored public workshops held across the state in December.

“The trucking community spoke and we listened,” said ARB Chairman Mary D. Nichols. “The good news is that we will not have to sacrifice the state’s air quality goals to assist fleet owners.

These amendments, which include more flexible deadlines and increased opportunities to access incentive funding, will further our emissions reduction goals by better ensuring that fleets can meet the requirements of the regulation.”

Nichols added that if the Board approves the changes, fleet owners who have already made investments to upgrade their vehicles will be provided with some benefits including additional time beyond what is currently allowed to keep trucks they have retrofitted.

“We recognize the huge investments that many business owners have already made in order to meet the requirements of the Truck and Bus Regulation,” Nichols said. “Their efforts have gone a long way toward helping us to meet our mandatory deadlines and we laud them for what they have accomplished.”

The proposed amendments provide additional regulatory flexibility to small fleets, lower mileage fleets and fleets in certain areas that have made substantial progress towards cleaner air. If approved, the amendments would better protect the emissions benefits of the regulation that are necessary to meet California’s air quality obligations under the federal Clean Air Act, as well as the goals of the ARB’s Diesel Risk Reduction Plan.

The proposed changes include:

* A longer phase-in period for diesel particulate matter (PM) requirements for trucks that operate exclusively in certain rural areas with cleaner air;

* Additional time and a lower cost route for all small fleet owners to meet their PM compliance requirements, while reopening opportunities for these fleet owners to apply for and receive public incentive funding;

* A compliance route for owners currently unable to qualify for a loan to finance required upgrades;

* Adjusted schedules for low-use vehicles and  certain work trucks;

* Recognition of fleet owners who took action to comply by providing additional “useable life”

for retrofit trucks and reducing near-term compliance requirements.

Overall these amendments would also ensure that, by 2020, the annual emission reductions would be at the same level as with the existing regulation.

Fast Facts on Diesel Emissions:

* Diesel exhaust contains a variety of harmful gases and more than 40 other known cancer-causing compounds. In 1998, California identified diesel particulate matter as a toxic air contaminant based on its potential to cause cancer, premature death and other health problems.

* The Truck and Bus Regulation (Regulation) was adopted in 2008 to clean up harmful emissions from nearly all heavy-duty diesel trucks operating in California. The Regulation was amended in

2010 to provide economic relief to truckers affected by the recession, particularly small fleets, by delaying the first compliance requirements by one year and extending the time the truck could be operated before needing to be replaced.

* Approximately 1 million trucks operate annually on California highways. Roughly 625,000 are based out of state. Of the remaining 400,000 registered in California, about half are in small fleets of three or less.

* The Regulation currently requires most heavy trucks in California to install soot filters or upgrade to newer models with filters by Jan. 1, 2014, and that nearly all trucks have them installed by Jan. 1, 2016.

* For small fleets (three or fewer vehicles), Jan. 1, 2014, was a critical compliance milestone because for the first time at least one vehicle in each fleet needed to comply.

* At its October 2013 meeting, the Board heard an update on the Regulation and agreed with staff’s proposal to move forward with a number of near-term strategies to provide flexibility while not compromising the overall reduction and health benefits to be achieved by the Regulation.

* In 2000, the ARB adopted its Diesel Risk Reduction Plan, a blueprint for developing regulations to address diesel emissions from all sources including garbage trucks, urban buses, construction equipment, port trucks and fuels. For more information, see Diesel Risk Reduction Plan

Top Tips to Improve Your Fuel Economy

1. Take a Chill Pill

It turns out aggressive and generally aggravated driving can really come back and hit you in the pocketbook. All that quick accelerating and decelerating during freeway driving is slurping down33% more of your gasoline according to  ! So maybe get out the door early and skip the “makes-me-want-to-speed” double espresso shot until you get to work.

2. Maintain Your Ride

Proper care that follows your car’s prescribed maintenance schedule is key to keeping your fuel usage in the optimal range. Clogged filters or faulty spark plugs can adversely affect your gas mileage; so tune ‘er up!

3. No Junk in Your Trunk

This is an obvious one.  Many of us forget to think about how excess weight will use extra gas. That means those golf clubs in your car, or the three kids seats for when your grand-kids visit! Take them out! Also, a roof rack will not only add weight but also drag, decreasing your car’s gas mileage even more. Not going camping any time soon? Remove the roof rack.

4. Wash Your Car

Yes, seriously. All that dirt creates drag, which takes more power to push the vehicle through the air. At engineer Tom Wagner, Jr. reported a 7-percent improvement in fuel economy, from 15 to 16 mpg, during a 1,600-mile road trip with his fancy-schmancy clean car.

5. Keep Your Tires Properly Inflated

You’ve heard this one before, and it’s still true. California passed a law that all automotive service providers are required to check and inflate each vehicle’s tires to the recommended tire pressure rating, with air or nitrogen, as appropriate, at the time of performing any automotive maintenance or repair service. This can help fuel economy up to 3.3%.

6. Learn When to Vent

Air conditioning takes extra gasoline to power, so while you are driving around town, have the windows down. However, when a car is traveling at high speeds, drag from open windows takes extra gasoline.  For freeway driving air conditioning makes the most “cents.”

7. Combine Trips

Is the grocery store right next to the community pool? After dropping the kids at their swimming lesson, you can make your a trip to the grocery store. Making one trip for many tasks saves you time and gasoline.

8. Vital Not to Idle

Just sitting there? You are getting 0 miles to the gallon! It is indeed more fuel efficient to restart the car than to have it running.
