The performance of Engine depend upon the proper combustion of fuel with sufficient air.
oxygen availability in air, depends upon the height from sea level.
As we are going in hill areas the air availabilty is less,which leads to less availability of oxygen.
Even we are having turbochargers to boost up the performance, there is little performance drop in engine, Due to unavailability of sufficient oxygen in air, the proper combustion not takes place.
Owners of vehicles with diesel engines looking for high performances parts can go to a couple of quality sites on the web to purchase them. These sites are Advanced Diesel and Pure Diesel Power.
Steve's Automotive, located in Portland at; 22 NW and 14th, specializes in high performance diesel engines. Their phone number is (503) 227-4112.
Diesel engines have much more torque at low rpm.
In a diesel engine, the air pressure during the compression stroke can reach around 30 to 50 psi (pounds per square inch), but it can be significantly higher in some high-performance engines, sometimes exceeding 100 psi. This high pressure is crucial for achieving the necessary temperature to ignite the diesel fuel, as diesel engines rely on compression ignition rather than spark plugs. The compression ratio in diesel engines typically ranges from 14:1 to 25:1, contributing to the high pressures observed.
It reduces climb performance.
The difference between diesel and high speed diesel is that high speed diesel has special cleaning detergents added to it. These detergents clean the injectors, which makes the vehicle run better.
Not necessarily, they have different uses. Gasoline is better in small, high revving engines and diesel is much better for larger, slower engines in general.
That is condensation from hot engines in cold air.

Well this all depends on what type of engines are supplied in these buses. Usually buses use diesel due to the high weight load that that are put on the engines. Diesel engines have better compression and can usually provide more torque to do work with all those people on board. Here is a good read on Diesel engines....(link)
High Flash Speed Diesel is not recommended for use in engines designed for earthmoving machinery. These engines typically require fuel with specific properties, including a higher cetane number and lower volatility, to ensure optimal performance and reliability. Using inappropriate fuel can lead to engine damage, reduced efficiency, and increased emissions. Always consult the manufacturer's specifications for the correct fuel type.
Diesel engines use a compression ignition system, where air is compressed to a high pressure and temperature before diesel fuel is injected directly into the combustion chamber, leading to spontaneous ignition. In contrast, petrol engines utilize a spark ignition system, where a mixture of air and petrol is pre-mixed and drawn into the combustion chamber, then ignited by a spark plug. This fundamental difference affects their efficiency, performance, and emissions, with diesel engines generally being more fuel-efficient and providing more torque at lower speeds. Additionally, the air-fuel mixing process in petrol engines is more uniform compared to the direct injection in diesel engines.
