Which is best, petrol or diesel? Stephen Ottley puts both through their paces.
If there is a poster child for a successful image makeover in the auto industry, then diesel fuel is it. In short order it has gone from dirty, smelly truck fuel to powering the winners of the prestigious Le Mans 24 Hours race for the past five years.
Less energy, costs, downtime and emissions. More flexibility and uptime.
Approximately 1.87 MW of high-grade heat is available when the engine operates at its maximum capacity of 1.57 MW brake power. The overall energy balance for the engine operating at 100% capacity can be illustrated in the form of a Sankey diagram (Fig. 3.14).
Synergy Diesel Efficient fuel for passenger vehicles
Diesel engines are more economical than petrol engines, which still haven’t caught up despite advances like direct injection. So what exactly is the difference between petrol and diesel engines and how do diesels work?
Diesel is the Platform to Deliver Energy Efficiency
Diesel engines are prided for their durability and performance. They are also known as one of the most fuel efficient technologies around. The latest clean diesel technologies build on diesel’s efficiency accolades by saving even more fuel and contributing to energy policy and air quality goals. Further advancements in diesel technology will continue to polish diesel’s efficiency credentials.
If diesel engines are more efficient why do most cars have gasoline engines?
The two things working in favor of diesel engines are better fuel economy and longer engine life. Both of these advantages mean that, over the life of the engine, you will tend to save money with a diesel. However, you also have to take the initial high cost of the engine into account. You have to own and operate a diesel engine for a fairly long time before the fuel economy overcomes the increased purchase price of the engine. The equation works great in a big diesel tractor-trailer rig that is running 400 miles every day, but it is not nearly so beneficial in a passenger car.

In order to meet the stricter CAFE/GHG standards, the Agencies acknowledged the potential need for vehicle manufacturers to include diesels in their product strategies. According to the TSD, several vehicle manufacturers have indicated to the Agencies that diesels will be part of their strategy to meet the midterm goals. Manufacturers that produce more diesel-engine-powered vehicles have also informed the Agencies that they expect diesel technologies to be part of a feasible strategy for reducing fuel consumption, carbon dioxide, and NOx emissions in the future.

Fuel Efficiency in a Time of Cheap Diesel
While there is no consistent period of time that all fleets keep their tractors, most fleets will keep them for between four and 10 years. That makes it important for fleets to be concerned about the future price of fuel. Fuel may be cheap now, but how much will it cost in a few years? Even during times like now with relatively low fuel prices, fleets must understand how decisions today will impact fuel costs for many years in the future.
Step 1: Make your car more fuel-efficient
You can drive the same distance in the same car, without slowing down, but using less fuel – better for your wallet, better for the environment. The key is to drive smoothly. Here are the seven tips you need to know.
