NTK cites three advantages that the MAP sensor brings to drivability

Company specialist justifies the technological evolution of these sensors due to their wide use in engines with direct or indirect electronic injection systems

São Paulo, July 2024 – The NKT, brand of Niterra, Japanese multinational that also owns the NGK brand, which specializes in components for ignition systems, highlights the three main driving and fuel economy benefits of an automobile offered by Manifold Absolute Pressure sensors (MAP).

1. Motor efficiency: MAP sensors are fundamental to the electronic injection system, Especially for those who work with the Speed Density strategy, where the mass of air entering the engine is calculated through information such as absolute manifold pressure, and admitted air temperature. This system is widely used in domestic vehicles, because it is highly reliable and accurate, promoting smooth engine response and driving efficiency.
2. Reduced fuel consumption: through the information provided by the MAP sensors, it is possible to calculate the correct amount of fuel to be injected, optimizing engine performance and reducing fuel consumption and pollutant emissions.
3. Turbo pressure control: on turbocharged engines, that are currently present in the most modern engines, MAP sensors play a crucial role in precisely controlling overfeed pressure, Also known as turbo pressure, ensuring better control of the engine's turbo phase and optimal engine performance in all driving conditions, in addition to providing greater engine and turbocharger durability.

Technological developments in MAP sensors

To achieve exceptional performance in the mentioned features, MAP sensors have evolved significantly within the technology of injection systems, can have analog signal, Digital or Boost Pressure type, applied to turbo engines, which reflects the wide range of options available today. In this context, The automotive industry focuses its efforts on minimizing environmental pollution and maximizing energy efficiency, which is closely linked to fuel consumption.

"The proliferation of turbocharged engines is a contemporary reality, requiring sensors to live up to these new standards. Therefore, Quality, Accuracy and proper application of sensors are aspects of critical importance in today's automotive engineering", afirma Hiromori Mori, Niterra Technical Assistance Consultant.

NTK's MAP sensors were developed to meet the requirements of the main vehicles found in the Brazilian market. This product line is especially dedicated to meeting the demand for high-quality automotive parts, intended for the aftermarket. Beyond MAP sensors, NTK provides a wide range of sensors for the injection system that contribute to the drivers' driving experience.
