Lab Q&A: Diesel Exhaust Fluid

Question: What is DEF? Answer: Diesel Exhaust Fluid (DEF) is a nontoxic, urea-based chemical reactant necessary for the functionality of Selective Catalytic Reduction (SCR) systems, which reduce oxides of nitrogen (NOx) emissions. Most major engine manufacturers are using SCR systems to meet 2010 emission regulations. Here’s how it works: DEF is injected into the hot

Gasoline Direct Injection

Way back when Gasoline direct injection (GDI) was first used in 1925 on the Hesselman engine. Jonas Hesselman designed the engine to start on gasoline and then switch over to run on diesel or kerosene. But in 1952, Bosch developed the first automotive direct injection system that actually ran on gasoline. Mercedes Benz wasn’t far

Lab Q&A: Continuously Variable Transmissions

Question: Why do we need a new CVT Conditioner if BG’s CVT Fluid offers unsurpassed wear protection? Answer: BG Universal Synthetic CVT Fluid, PN 318, is designed for use in only belt-driven CVTs. These CVTs exhibit modest thermal stress and require good surface-to-surface metal protection. CVT units produced by GM, Chrysler, Nissan, Mercedes Benz, Subaru, Lexus,

What you need to know about ethanol

Does the use of ethanol reduce fuel economy relative to conventional gasoline? Yes. The consumption of fuel relative to miles/kilometers traveled is directly related to the energy content. Conventional gasoline has an average energy content of 114,000 BTU/gallon. But, energy content of conventional gasoline can vary up to 7 percent from one fill up to the

Lab Q&A: “Synthetic” Products

Question: What makes a product “synthetic”? Answer: Synthetic is derived from the word synthesize, referring to a process that involves taking a set of raw materials and making a finished good. Typically, the process includes a series of chemical or manufacturing steps that produce a chemical compound with planned and predictable properties. These processes usually

Diesel emissions technologies

According to the EPA, “more than 11 million diesel engines in operation today do not meet EPA’s new clean diesel standards, yet these engines can continue to operate for 20 to 30 years” (www.epa.gov/cleandiesel). Environmental reform is one of the most important issues facing the country today. Smelly fleets The EPA developed the National Clean

Tech Trends: Fuel System Technologies

With the fickle availability of refined fuels and the price of crude oil ever on the rise, fuel economy is a concern now more than ever. And as a result, fuel system technologies are undergoing dramatic change. Recently, major vehicle manufacturers are focusing primarily on improving fuel economy through better weight-to-power ratios while reducing exhaust

Gearing Up For CVTs

The automatic transmission has held the distinction of being the most popular type of transmission for vehicles for more than 75 years. However, the continuously variable automatic transmission (CVT) and other new-age designs are slowly gaining popularity. By 2012, CVTs are expected to have a 20 percent share of the Japanese market, a four percent

BG Biodiesel Fuel Conditioner Makes Biodiesel Palatable

With diesel fuel prices at historic highs, desperate drivers are scrambling to find ways to stay on the road. “They are pouring transmission fluids, used solvents, suntan lotions, anything they can find into their tank to lower fuel costs,” says Mike Belluomo, BG’s Product Technical Services Manager. Would you like fries with that? The hottest

Coolant is long lasting, but keep an eye on it

When the first cold snap of winter or the first hot days of summer arrive, a car owner wonders: Do I have enough coolant to keep from freezing up or boiling over? Is it still any good? When was the last time I changed it? For that matter, when was the last time I checked
