Bully Dog Propane Injector Boosts Diesel Performance

Bully Dog Propane Injector Boosts Diesel Performance ENGINES Engines 26-1-41 After a turbocharger on his pickup's diesel engine exploded and took out a couple of pistons, Brian Wray, Kalispell, Montana, figured there had to be a better way to improve diesel power and fuel efficiency. The solution he found is called "Bully Dog". "It's a propane injection system that works on diesel engines," he explains. Since he installed the system on the 6.9L engine in his Ford F250, he claims he's getting 4 mpg better fuel efficiency, and considerably more power. Wray uses his pickup to pull a 4-horse trailer and for basic transportation. "I bought it used and like all diesels, it smoked a little. After I installed the Bully Dog injector, it cleared up the diesel smoke and the exhaust smells like LP burning rather than diesel." Priced at under $800, it's expensive but still $1,000 to $1,500 less than a turbocharger, notes Wray. He says the inector is easy to install. "You need a little working knowledge of electrical schematics and a fair sense of plumbing," he notes. "It requires installing a sending unit in the oil line. That's a safety measure that shuts off the propane flow if oil pressure drops. That way, the propane is shut off when you shut off the engine." He says it also requires installing propane tanks somewhere in the vehicle. Materials and tanks for that cost him about $100. Besides cutting his diesel fuel use, Wray notes that the Bully Dog injection system uses less than 2 gal. of propane for every 20 gal. of diesel fuel he burns, even when he's using it hard. Philip Klassen, who with his brother Michael, developed the Bully Dog propane injector, says it will work on any diesel engine. "Injecting a small amount of propane results in a more even amd more complete burn of the diesel, so smoke and emissions are both reduced," he says. They sell versions for all diesel-powered pickups. Klassen says the system actually works better on a turbocharged engine than on a naturally aspirated one. "We've sold them for tractors and combines, too," he says. "And this past fall, we sold one for a cotton picker." Klassen says people are often a little leary of a system that uses propane at first. "But it's actually quite safe," he insists. "With the oil pressure safety shut-off switch, the flow of propane is automatically cut when the engine is stopped or if there's some kind of engine malfunction."
