Oil hole to the engine head for lubrication of the components over there. Engine oil drains ports and the thermostat coolant gallery. Head mounting bolt ports. Automobile Engineering tutorials

How hydraulic ram works.

This video explains about the working of a hydraulic ram or hydraulic cylinder.
The hydraulic ram is used in a hydraulic circuit for accomplishing a particular work. It actually converts the hydraulic pressure energy to mechanical energy "productive work". This video clearly explained how a hydraulic ram works and how the resultant components linked with it moves for carrying out a work. It also covers the function and working of the control valve or valve block and its spool movement resulting in the corresponding movement of the ram.

Drifting Vs Oversteer.

This video compares Drifting with Oversteer.
When you drive and reach the limits of grip on a corner, two scenarios called oversteer happens and controlled over steer is drifting. Both these scenarios are explained with animation in this topic.

Drifting explained.

This video explained about Drifting.
Drifting is the process of controlling the over steer. While taking a turn when the tyre looses the traction or grip, it can result in oversteer. This over steer is controlled and made to advantage is called "Drifting".

Dismantling and explained a Starter motor

This video helps to identify the internal component of a starter motor. In this video a starter motor is dismantle and assembled back.Mechanical Engineering tutorials videos
A starter is a type of electrical machine which converts electrical energy into mechanical energy. Engineering tutorials
The electrical energy is obtained from the battery. When the starter switch is operated, current flows through the starter (the field coils and the armature conductors) and two magnetic fields are set up.

Understeer explained.

How to use a hydrometer.

This video shows how to check the specific gravity of a lead acid battery using a hydrometer.
Mechanical Engineering tutorials videos
As you can see in the video, hydrometer consists of a glass tube which has a float inside. On the bottom of the hydrometer we have the suction tube, for sucking electrolyte. On the top we have a rubber bulb, which is squeezed to suck the electrolyte into the hydrometer tube.
As the electrolyte enters the tube, the float tends to move. So we can get the specific gravity at the scale of the float where the electrolyte rests.   Hydraulic tutorials

How to install an Air filter.

The videos shows, how to fix an air filter inner and outer element.
Mechanical Engineering tutorials videos
Air filter is one critical part of an engine. This is the unit which cleans the air which is sucked from the atmosphere to be supplied to the Engine inlet manifold. If this air is not effectively cleaned (has dust). It will result in reduced efficiency and gradual failure of the engine. Engineering tutorials

How to check hydraulic pressure of JCB.

Hydraulic pressure checking of a back hoe loader machine is shown and explained in this video.Hydraulic tutorials
Hydraulic pressure is the most critical parameter which determines the efficiency of hydraulic machinery. The MRV -- main relief valve controllers the hydraulic pressure. The main relief valve is set to protect the hydraulic pump from back pressure. It is set at a particular pressure which the hydraulic pump can hold. If more back pressure comes in, it opens up to release it.Engineering tutorials

Mechanical Engineering tutorials videos
ABS -Anti lock breaking system is an advanced braking system used in modern vehicles which is hydraulically operated.
Without ABS: It's true that the vehicle can slow down quicker with ordinary braking system compared to the ABS. Automobile Engineering tutorials But it compromises on the vehicle stability while doing so. The vehicle can skid in this system and cause accidents. Hydraulic tutorialsEven steering lock can happen, which will restrict the driver from steering off the vehicle to avoid a collision.
