Why not diesel engines are not preferred in commercial ?

Why are diesel engines  not preferred in commercial ?



Commercial vehicles see robust sales in January 2018


1.Diesel engines, because they have much higher compression ratios (20:1 for a typical diesel vs. 8:1 for a typical gasoline engine), it tend to be heavier than an equivalent gasoline engine.

2.Diesel engines also tend to be more expensive.

3.Diesel engines, because of the weight and compression ratio, tend to have lower maximum RPM ranges than gasoline engines .This makes diesel engines high torque rather than high horse power, and that tends to make diesel cars slow in terms of acceleration. 

4.Diesel engines must be fuel injected, and in the past fuel injection was expensive and less reliable.

5.Diesel engines tend to produce more smoke.

6.Diesel engines are harder to start in cold weather, and if they contain glow plugs, diesel engines can require you to wait before starting the engine so the glow plugs can heat up.

7.Diesel engines are much noisier and tend to vibrate.

8.Diesel fuel is less readily available than gasoline.

What is the MAGNETO IGNITION SYSTEM? | WORKING | knowledgeaboutautomobile957

MAGNETO IGNITION SYSTEM Magneto is a special type of ignition system with its own electric generator to provide the necessary energy for the system. It is mounted on the engine and replaces all the components of the coil ignition system except the spark plug. A magneto when rotated by the engine is capable of producing a very high voltage and it does not need a battery as a source of external energy. The high tension magneto incorporates the windings to generate the primary voltage as well as to step up the voltage and thus does not require a separate coil to boost up the voltage required to operate the spark plug. Magneto can be either rotating armature type or rotating magnet type. In the first type, the armature consisting of the primary and secondary windings all rotate between the poles of a stationary magnet. whilst, in the second type the magnet revolves and the windings are kept stationary. A third type of magnet to called the polar inductor type is also in use. In the polar in...

Introduction to LiDar Sensors // Self Driving Cars //Autonomous vehicle // Sensor

  1 / 3 Lidar — Light Detection and Ranging 2 / 3 Autonomous vehicle 3 / 3 Caption Three What is Lidar LiDAR, or light detection and ranging, is a popular remote sensing method used for measuring the exact distance of an object on the earth’s surface. Even though it was  first used in the 1960s  when laser scanners were mounted to aeroplanes, LiDAR didn’t get the popularity it deserved until twenty years later. It was only during the 1980s after the introduction of GPS that it became a popular method for calculating accurate geospatial measurements. According to the  American Geoscience Institute , LiDAR uses a pulsed laser to calculate an object’s variable distances from the earth surface. These light pulses — put together with the information collected by the airborne system — generate accurate 3D information about the earth surface and the target object Types of LiDAR Systems Works during day ...
