Safety is the most important aspect of any gas system. It was our top priority from the beginning, when we were developing Fuel Fusion. We fully understand that other aspects are not important if the installation puts the user, the engine or the surrounding environment on the risk. Savings and other benefits are less important in this context. That’s why we’ve always put the safety first.

A key component in this regard is the EGT (Exhaust Gas Temperature) sensor. Its task is to measure the temperature of the exhaust gases leaving the engine and entering the exhaust pipe. It is a crucial sensor that provides us with information about the conditions in the combustion chamber. If the exhaust gas temperature increases, it’s a crucial indicator that something is wrong. Therefore, the EGT sensor should be installed as close to the engine as possible to detect any alarming symptoms and send a signal to the controller.

Why is exhaust gas temperature so important?

Exhaust gas temperature directly depends on the conditions inside the combustion chamber. If the engine is operating properly, the internal temperature will be within normal limits, which will also impact exhaust emissions.

If this process is disrupted and not proceeding as expected – for example, due to an incorrect fuel mixture ratio – the EGT sensor will be able to quickly detect any problems and will send an appropriate signal to the gas controller. This protects engine components from overheating and prevents any damage.

EGT Sensor Installation

The sensor’s tip is placed inside the vehicle’s exhaust pipe. To install it, it is need to drill a threaded hole into which the sensor is screwed. The closer the sensor is to the engine, the more accurately its readings will be and show the more accurate the engine condition. Therefore, a threaded hole should be drilled at the beginning of the exhaust pipe.

The other tip of the sensor should be connected to the system’s wiring harness, enabling it to communicate with the Fuel Fusion controller.

EGT Sensor – Specifications

The principle of operation of an EGT sensor is simple in theory. These components operate on the principle of comparative measurements. The EGT probe consists of two wires made of different types of material. Their ends, form a measuring junction on one end, and terminals on the other, allow for the measurement of thermoelectric voltage. Its value is proportional to the temperature difference at the ends of the wires. This is known as the Seebeck effect – if two dissimilar metals are connected, the temperature change generates a measurable voltage. This happens because electrons move from one wire to the other. Their movement amount depends on temperature, so exhaust gas temperature can be determined based on this. Simply put, the potential difference between the two wires allows for the measurement.

The accuracy of the obtained results is crucial. Choosing a probe that can provide reliable results is a key element in selecting accessories for a autogas system. When designing Fuel Fusion, we placed great importance on safety and protecting the engine from the risk of damage. Furthermore, the sensor must be resistant to damage, vibration, extreme temperatures and corrosion.

That’s why the choice of this component was not accidental. The sensors we use provide reliable results and help protect the engine from any damage.

Summary

Choosing the highest quality components for Fuel Fusion system is of paramount importance to the safety of its user.. That’s why, during the system design phase, we paid special attention to the selection of safety features. While many EGT sensors are available on the market, some of them suffers from build quality issues. The most common issues include poor durability – rust, mechanical damage, insufficient shock resistance and measurement inaccuracy.

The components included in Fuel Fusion systems always come from reputable manufacturers, and the choice of the EGT sensor was no exception. To provide our customers with the best quality, we use sensors that perform exceptionally well – in all diesel-powered machines, whether they’re generators, trucks, coaches or other vehicles.
