Diesel engines are often chosen for their excellent low-end power (high torque output) and long-term durability. One of the major differences between diesel and gasoline engines is how the fuel is delivered. Diesel fuel is injected through high-pressure rails directly into the combustion chamber of each cylinder. This is called direct injection and is monitored very closely to ensure the precise ratio of diesel fuel and air is injected for optimal combustion and maximum power.

While diesel engines have been around for a long time, engineers are constantly working to improve the fuel delivery technology of diesel engines. Why? The obvious reasons, actually – the results are more power, greater durability and cleaner emissions. Here are some of the major improvements that have been made…

Here’s the truth no matter how you cut it: a vehicle won’t run right if it’s not consistently getting the fuel it needs. Consistency is key, because the gateway to today’s fuel systems are the fuel injectors that open and close in millionths of a second to spray a controlled dose of fuel into the engine. Here are three typical symptoms that indicate a fuel system problem, usually because the fuel injector tolerance is no longer in balance.

Power Loss: Power loss, as well as alternating high and low engine revving and sluggish acceleration, can be a clear sign of fuel injector problems. This is often the result of fuel injectors being clogged or dirty, which impedes fuel delivery.

The Fast, the Present, and the Future
Show Report by Marissa P.

The North American International Auto Show (NAIAS) kicked off in Detroit, Michigan a couple weeks ago and as always the automakers pulled out all the stops trying to outdo one another. Nearly everyone premiered new takes on old classics and even gave us a glimpse of the future.

Dodge certainly didn’t shy away from the competition with its display of the 2018 Dodge Demon. The Demon proudly boasts that it is a drag strip-ready car straight from production. Don’t get your hopes too high though, as-is the car won’t pass an NHRA safety inspection it will need a few a few extras before you can head down one of their tracks.

Ford, however, wasn’t going to…

Ah, engine “response.” That elusive term that is hard to define, but you know it when you feel it.

Simply put, the term “engine response” refers to how quickly your engine responds to a change in throttle position. Ideally, your engine reacts instantly when you push on the accelerator pedal and lets power drop back down the moment you let off.

As your engine gets older, responsiveness can begin to drop, causing hesitation and surging when you don’t want it. Correct engine responsiveness can also help reduce fuel economy, as your engine only develops the power you need right when you need it.

To help ensure your engine stays responsive like when it was new, our engineering and tech support teams here at Rislone have put together…
