When comparing diesel and gasoline engines, diesel engines are ultimately considered superior to gas engines in heavy-duty vehicles because of their improved fuel efficiency and longer life expectancy. They are often the preferred engine type for vehicles such as emergency vehicles, bulldozers, dump trucks, excavators, ships, semi-trucks, and trains.
Diesel vs Gas: Understanding the Differences
Though both diesel and gas engines are internal combustion engines, there are differences in their operations that make diesel engines more suitable for industrial vehicles. The differences come from:
- The higher energy density of diesel fuel
- The greater compression of air by diesel engines
- The absence of spark plugs in diesel engines
These differences contribute to the following characteristics:
- Life expectancy. Diesel engines compress air almost twice as much as gas engines (approximately 20:1 vs 10:1). As such, engine parts like block and cylinder heads, crankshafts, pistons, and valves in diesel engines are designed to be more robust than gas engines. This higher compression also results in more complete combustion of the fuel than what is found in gas engines, so diesel engine exhaust is less corrosive. This contributes to a longer service life for engine components.
- Fuel costs and efficiency. Due to increased air compression, diesel engines also operate at higher temperatures than gasoline engines. This results in a more efficient conversion of thermal energy to mechanical energy. Diesel engines are about 15–40% more efficient than gas engines and diesel fuel is about 15% cheaper than gasoline. Therefore, the per-mile cost of diesel engines is significantly lower than gas engines.
- Torque/horsepower. The high compression ratio of diesel engines gives them an ability to create a higher torque at lower engine speeds. Also, diesel fuel has 12–16% more energy content than gasoline. These factors make diesel engines ideal for heavy load applications that require a steady, high torque.
- Maintenance costs. Diesel engines do not have spark plugs. Diesel is also a much better lubricant than gasoline. When considering emissions from diesel versus gasoline, the more complete ignition of the diesel fuel produces less pollutants and corrosive agents. Diesel engines operate at a lower rpm than gas engines. All these factors contribute to reducing the maintenance costs for diesel engines.
The Importance of Proper Engine Maintenance
Diesel fuel easily picks up contaminants due to its high viscosity. Periodically changing the oil and oil filter will clean accumulated dirt from inside the engine. It is also important to keep an eye on oil consumption as an early indicator of harmful oil leaks. These should be quickly detected and promptly fixed.
Diesel engines require a steady supply of clean air to maintain peak performance. Dirty filters reduce airflow to the engine, so it is important to regularly inspect and change air filters. This is especially important for dump trucks, military vehicles, and boats that operate in harsh environments.

Over the course of June – National Safety Month – the National Safety Council raised awareness of the most common causes of injury and death in the workplace and helped companies develop effective strategies to ensure the safety and health of their workers. As a proud supporter of National Safety Month, we wanted to take a moment to further that mission by sharing some of our safety solutions with our customers.
How Can You Improve Workplace Safety?
Workplace safety should be a leading priority for any company, but it doesn’t need to be a challenge. Taking these simple steps can help you keep your workplace is as safe as possible at all times.
1. Follow OSHA Guidelines
The Occupational Safety and Hazard Administration (OSHA) was founded to protect American workers from harmful conditions by establishing safety standards for every major industry and educating businesses on the best practices for their workplaces. Regardless of your field, be sure to acquaint yourself with any relevant OSHA regulations and follow them as closely as possible.
2. Post Signs, Labels, and Warnings throughout the Workplace
Workplace accidents are usually the product of carelessness or ignorance rather than deliberately unsafe behavior. Outlining the precautions that employees need to take before entering a certain space or handling a particular piece of equipment can significantly reduce the risk of injury or death on the job.
3. Employee Training and Certification Programs
At the end of the day, the best safeguard against occupational hazards is a well-informed staff. All employees should receive thorough instruction in any tasks or processes in which they’re involved, and any functions that could endanger the entire workplace if performed improperly should be limited to employees with special certifications.
Mobile Safety Products to Add to Your Worksite
While these common sense measures can improve safety throughout the workplace, recent technological innovations can prove an invaluable addition to your company’s safety procedures. At Central Diesel, we’re pleased to produce a number of mobile safety products that can further strengthen your efforts to protect your employees.
Our mobile safety solutions are designed to shore up your safety strategies wherever necessary. Our Mobile Surveillance System, for example, constantly monitors any space that requires heightened visibility, helping you ward off intruders or unauthorized employees. Similarly, our Mobile Lighting Systems can increase visibility in any environment in which light is limited, eliminating a common cause of workplace accidents.
Following National Safety Month, it’s an ideal time to review and modify your safety strategies as necessary. Take the time to thoroughly assess your operations and speak with employees to identify possible risks and develop effective solutions to them. From conducting necessary trainings to investing in appropriate safety equipment, don’t hesitate to make needed changes.
At Central Diesel, we’re committed improving American companies with cost-effective safety products that provide lasting protection from any occupational hazard. If you’d like to explore our offerings, contact us today.
Even though experts believe that two decades of policy failures have stagnated the growth of the US manufacturing sector, it is still active enough to employ 8.8% of the national workforce and taken alone would be the ninth largest economy in the world. But if the golden era of manufacturing is to return to the shores of the country in earnest, a lot more than just infrastructural expansion and demand generation would have to be taken into account.
While the next eight years will see about three and a half million new jobs added to the sector, sadly two million of these vacancies will go unfilled.
There is hope for the future but to usher it in the United States needs more students interested in S.T.E.M careers, better knowledge transfer between employees, and a revamped perception of what careers in manufacturing are like in 2017.
The National Manufacturing Day (NMD) – a nation-wide endeavor undertaken the first Friday of every October attempts to hit the goals above.
Annually celebrated on the 6th of October, we’re taking a look at the impact of NMD and the contribution of our industry to manufacturing as a whole.
What Has the National Manufacturing Day Achieved?
Over the last six years, the National Manufacturing Day has seen the participation of hundreds of thousands of suppliers, manufacturers, and students. More than 2,100 factory tours have been organized, and in 2017 it is expected that 600,000 businesses and individuals will be associated with the event.
Thanks to the impact of NMD and a closer look at the changing face of American manufacturing careers, 81% students are more convinced that manufacturing can provide them with stable, interesting and well-paying jobs.
89% are also more aware of manufacturing opportunities in their communities, and 64% are more likely to pursue them.
Diesel Engines: Igniting the Manufacturing Spark
Almost all industries that are a part of the manufacturing sector look back at what businesses have achieved over the years when the National Manufacturing Day rolls around.
The diesel engine market is billions of dollars strong in the US, heavily contributing to both the manufacturing sector and the economy. With the Diesel Emissions Reduction Act, this number is only going to increase.
Moreover, without diesel engines, all aspects of manufacturing from the actual production of goods to their transportation suffer because other combustion set-ups consume more fuel, produce lower torque and are far less durable and resilient than their diesel peers.
Diesel engines save the manufacturing sector millions every year in maintenance and repairs.
