Indianapolis: Ford Motor Co. says its ever-growing portfolio of fuel-efficient products extends to commercial customers, including those interested in alternative-fuel vehicles to "green" their fleets.
Visitors to the annual National Truck Equipment Association (NTEA) show here earlier this week saw firsthand how Ford delivers the most comprehensive alternative-fuel solutions for commercial customers.
The wide variety of vans and trucks with alternative-fuel capability is backed by support for customers looking to switch their vehicles from gasoline power to another fuel, such as compressed natural gas or propane. By 2012, half of all Ford vehicles will be capable of running on alternative fuel.
"No other manufacturer offers the range of vehicles and alternative-fuel solutions combined with comprehensive support," says Len Deluca, director, Ford Commercial Truck. "We're bringing our commercial customers the solutions they need in this ever-competitive environment."
As businesses seek to be more environmentally responsible in all facets of their operations, greening a vehicle fleet is often a natural first step that can have an immediate and positive impact. There also are government tax credit incentives for fleets to convert to alternative fuels.
With the wide variety of requirements for commercial vehicles – such as application, payload and driving cycle – Ford has developed an expansive suite of vehicles and alternative-fuel choices.
"Our range of choices helps ensure customers can find the right product that best suits their needs," said Deluca.
For example, a battery electric vehicle (BEV) might be appropriate for customers with multiple short trips over the course of a day totaling less than 100 miles. CNG, LPG and flex-fuel vehicles have a range of about 300 miles before needing to be refueled. Biodiesel and hybrid vehicles stretch the range even further, up to 500 miles.
Types of fuels and their advantages
Here's a quick look at the types of fuels offered in Ford commercial trucks:
- Flex fuel: A flexible-fuel vehicle (FFV) is an alternative-fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with ethanol (E85), and both fuels are stored in the same common tank. Flex-fuel engines are capable of burning any proportion of the resulting blend as fuel injection and spark timing are adjusted automatically according to the actual blend detected by electronic sensors. E85 is the most common flex fuel and many Ford engines are capable of using E85.
- Biodiesel: Biodiesel refers to a vegetable oil or animal fat-based diesel fuel. Blends of biodiesel and conventional hydrocarbon-based diesel are products most commonly distributed for use in the retail diesel fuel marketplace. A system known as the “B” factor is used to state the amount of biodiesel in any fuel mix – 20 percent biodiesel is referred to as B20, for example.
- CNG (compressed natural gas): CNG is a fossil fuel substitute for gasoline or diesel. It is safer than other fuels in the event of a spill (natural gas is lighter than air, and disperses quickly when released). CNG is made by compressing natural gas, which is mainly composed of methane. It is stored and distributed in hard containers at a pressure of 2,900 to 3,600 psi. CNG is used in traditional gasoline internal combustion engines that have been modified to operate on CNG.
- LPG (liquefied petroleum gas): LPG is a flammable mixture of hydrocarbon gases, most commonly propane and butane. A powerful odorant is added so that leaks can be detected easily. As opposed to relying on foreign oil sources, approximately 90 percent of the United States’ propane supply is produced domestically. Propane is nontoxic and cannot get into the water table if there is a leak in the storage container.
- Hybrid: A plug-in hybrid electric vehicle (PHEV), also known as a plug-in hybrid, is a hybrid vehicle with rechargeable batteries that can be restored to full charge by connecting a plug to an external electric power source. A PHEV shares the characteristics of both a conventional hybrid electric vehicle, having an electric motor and an internal combustion engine, and an all-electric vehicle, also having a plug to connect to the electric grid.
- BEV (battery electric vehicle): A BEV uses chemical energy stored in rechargeable battery packs. As with other electric vehicles, BEVs use electric motors and motor controllers instead of an internal combustion engine for propulsion. The concept utilizes onboard batteries for propulsion and recharges the batteries using the electric grid.
Ford has developed and tested a CNG/LPG Gaseous Engine Prep Package to be installed by preferred upfitters, who install the CNG/LPG tanks and hardware. The engine comes with hardened exhaust valves and valve seats for improved wear resistance and durability for gaseous fuel systems, and Ford engineers work with the upfit companies to ensure consistent and reliable performance.
The new engine calibration maintains engine operating limits as specified for cylinder pressures, piston temperatures and engine speed, among others. Ford maintains the engine and powertrain warranty (five years/50,000 miles) and the upfitter is responsible for the system component warranty.
Customer-focused alternative-fuel offerings
"Our expanded portfolio of commercial products that can operate on alternative fuels has been developed based on the relationships we have with our customers and a commitment to supporting their sustainability strategies," said Rob Stevens, chief engineer, Commercial Products. "Going forward, we will continue to maintain this customer-focused strategy in the development of future technologies."
