Everything you need to know about hybrid cars

Posted by AJUSA: December 5th, 2017


- Hybrid cars combine the performance of an internal combustion engine with those of the electric motor, with a significant saving in fuel and the reduction of emissions to the atmosphere.

- AJUSA has already available the first video tutorial about the assembly of the full set of gaskets in a hybrid vehicle.


Hybrid vehicles allow a performance similar to conventional cars, but with a lower fuel consumption and, of course, lower emissions into the atmosphere.

The invention of the hybrid engine arises from the need to improve fuel savings in current vehicles and increase its power, combining the performance of gasoline engines with electric motors. Two power sources that can work together, separately or in parallel, depending on the type of use.


AJUSA already has available on its YouTube channel the video tutorial about the assembly of the complete set of gaskets in a hybrid car. The hybrid propulsion vehicle chosen for the explanation is the Honda Insight Hybric (LDA3). This model has a 1,339-cc engine and 88 hp gasoline and an electric 14 hp. VIDEO

Hybrid cars have a lower consumption because they are more efficient. According to data from Honda, the energy efficiency of a gasoline engine is 19% (that is, the remaining 81% of the energy coming from gasoline is lost in the form of heat). In a hybrid the efficiency increases up to 30%, thanks to the energy it can recover during decelerations, energy that reuses to activate the electric engine. The battery of the hybrid system is placed behind the rear seats.


Hybrid engine operation.

Although the basis is the same, there are some differences in how an internal combustion engine interacts with an electric one when they work together. Everything depends on the brand of the vehicle that has developed the system. Next, we indicate the systems of two of the main brands that have manufactured hybrid vehicles recently, although they’re not the only one.

In the Honda system, the combustion engine is the main one and it is always on. Meanwhile, the electric one is secondary and serves as a support at times when extra power is needed. As for the Toyota system, the electric motor is the main one. It is responsible for driving the stopped vehicle up to 35 km/h. The combustion engine would be the secondary, giving support to the electric at those times when extra power is required or when the battery level is low.

The transmission of power to the wheels of the Toyota system would be as indicated below. This type of engines is composed of gears that connect each of the engines to a chain that provides movement to the wheels. The electric motor is the one that initiates the movement of the vehicle by turning the outer gear, gaining speed without consuming a drop of gasoline. Instead, from a certain speed, the internal combustion engine is activated by turning the 4 gears of the power splitter and increasing the power of the car.

The system is completed with a central gear connected to a generator that charges the batteries, powered by the gasoline engine, which provides extra power to the electric motor. However, the operation of this type of vehicle may vary depending on the class of hybrid vehicle; in series or in parallel. 



Advantages of hybrid cars

  • Reduction of the emission of polluting gases and improvement of the efficiency in fuel consumption.
  • Less noise pollution. The engine of the hybrid car is much silent than a conventional one.
  • More autonomy than fully electric cars and faster recharging.
  • The electric motor of the hybrid car is very powerful. Also, the batteries are not discharged if something is left turned on.
  • The hybrid car can work for short trips using only the electric motor, e.g. driving around the city, where most of the petrol consumption is made.


Disadvantages of hybrid cars

  • The hybrid car has more difficulty when it comes to repairing a fault or simply making a revision.
  • The hybrid car weighs more than a conventional one due to the weight of the electric motor and batteries.
  • The batteries used by this vehicle are toxic.
  • The purchase price is still very high.


Other benefits of the hybrid car

Some of the advanced technologies that incorporate this type of hybrid vehicles, either in parallel or in series, include regenerative braking. A system to take advantage of the energy consumed during braking and transform it into electricity and then store it in the car’s batteries. The automatic ignition / shutdown of the engine or the assistant of the electric motor to provide additional strength in case of overtaking or steep roads, are two of the technologies incorporated in this type of vehicles that day by day is gaining followers.


AJUSA, at the forefront of the automotive sector, makes available to customers and professionals in the sector the video tutorial about the assembly of the hybrid car Honda Insight Hybric (LDA3). You will learn about the real engine of the vehicle how they assemble the AJUSA parts for this engine: cylinder head gasket, gaskets full set, cylinder head bolts kit, intake manifold, exhaust manifold and steam seal oil.
