Combined diesel-electric and diesel (CODLAD ) CODLAD ( CO mbined D iesel-e L ectric A nd D iesel) is a naval propulsion system in which an electric motor and a diesel engine act on a single propeller. The transmission system takes care of making one or both motors act on the propeller shaft. The CODLAD propulsion system is based on the use of
Diesel engines offer consumers 20-40% better fuel economy as well as more torque at a lower rpm than gasoline. Using biodiesel fuel in diesel engines helps further reduce emissions and reduces the
The combustion in diesel engines does not work with spark like gas engines do. Unlike gas engine diesel engines take only air through the intake valve during the first stroke, during the second stroke the intake valves are closed and air is compressed as the air is highly compressed on the cylinder the temperature of the air rises and almost reaches one thousand three hundred degrees
How gas and diesel engines work. At their core, gasoline- and diesel-powered engines work under the same principles. Both convert chemical energy from fuel into mechanical energy to produce movement.

Hot Shot's Secret Diesel Extreme. Diesel Extreme is the best additive in the game. This one adds seven points to diesel's cetane score (which again improves the fuel's combustion performance), and
When you burn hydrocarbons in air, their molecules split apart. The carbon and hydrogen combine with oxygen from the air to make carbon dioxide gas and water, while the energy that held the molecules together is released as heat. This process, which is called combustion, releases huge amounts of energy.

The Stirling Cycle. The key principle of a Stirling engine is that a fixed amount of a gas is sealed inside the engine. The Stirling cycle involves a series of events that change the pressure of the gas inside the engine, causing it to do work. There are several properties of gasses that are critical to the operation of Stirling engines:
On average, diesel engines are capable of around 250,000 to 300,000 miles, while gas engines usually clock out around 150,000 to 200,000 miles. This is mostly due to engine construction, as diesel engines—and all their components—are simple, robust, and built to support continuous use.
GPH = (0.4 x 300)/ 7.2 = 120/7.2 = 16.6 GPH. 300-hp Gasoline Engine Example. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH. Keep in mind that these formulas apply when the engine is making peak horsepower, which usually is near wide-open throttle. Fuel consumption will be decreased at cruising speeds.
For one, gasoline is far easier to store. Hydrogen is incredibly dense in terms of energy to volume. That means it takes up far more space in a combustion chamber (30% to 1-2%), which reduces its
There are however, a few differences. First, a direct injected engine is more sensitive to the gasoline quality, considering the design. A high pressure fuel pump is driven by a camshaft and this friction point is lubricated by engine oil. Ford EcoBoost high-pressure fuel pump. This means that a low oil level or lack of oil changes can cause
The main difference between winter- and summer-grade gasoline is vapor pressure. Gasoline vapor pressure is important for an automobile engine to work properly. During winter months, vapor pressure must be high enough for the engine to start easily. In the summer, a lower vapor pressure is required in many areas to reduce air pollution.
Diesel fuel has a higher energy density than gasoline. This means that for equal volumes of both fuels, the diesel stores an average of 15% more energy, but that is not the only way diesel engines
A lot of diesel pumps are separated from the unleaded pumps, which could also prevent pumping the wrong fuel. If you had a gas tank full of diesel fuel, the fuel injectors in your engine would inject the diesel fuel into the engine's cylinders. The spark plugs would fire, but nothing would happen after that.
