Emission Sensor

Emission sensor is an electronic device used to know the proportion of oxygen in the liquid or gas mixture. It finds its applications in the automotive and medical devices. The DEP (Detroit Engineered Products) emission sensor has various applications and advantages in the automotive industry as it helps to reduce emissions from the vehicles, contributing less to the pollution caused by vehicles. It also used for diving application, to measure the oxygen levels in the cylinder while diver goes deep down in the sea.

In the automotive industry, the emission sensor is mounted inside the exhaust manifold to supervise the unburned oxygen levels while the emissions are out from the engine. The sensor sends a voltage signal according to the reaction taking place in the exhaust; this gives an idea about the air-fuel ratio whether the mixture is burning rich or lean. Tampering of this signal can lead to wrong readings and malfunction of the emission sensor, so due care must be taken every time. Further, it can also set the air-fuel ratio such that the catalytic converters operate at their highest efficiency. In addition to this, the emission rates can also be controlled which reduces the amount of unburnt fuel and nitrogen oxides in the atmosphere. It is also used to determine the oxygen levels in some medical devices like respirators, anaesthesia monitors and oxygen concentrators. But scientist’s use a little different approach in this field.

CAD Morphing

Image
Usually in the design cycle, the simulations and the FE modeling are carried out once the concept CAD has been generated. Due to the necessity of reducing the concept design iteration, it will be significantly critical if the concept changes are made in the FE modeling itself causing the time required for CAD generation off cycle. Morphing, as the name would suggest, is an adaptation of giving shape to a new form. During major concept design changes, a source of major time consumption is the time taken between the CAE teams and the design department. CAD Morphing can significantly reduce the CAD data generation time since the data can be fed from available existing donor CAD Data, and the Optimized Finite Element and CFD data can be communicated to the design department directly as morphed CAD data. DEP (Detroit Engineered Products) CAD Morphing solutions allow companies to make critical die adjustments by manipulating complex surfaces while maintaining the critical product c

Weight Optimization

Image
Weight optimization is a technique used mostly in the automobile industry to get the optimum weight or less weight of the desired part or product. Here parametric optimization also comes in handy to get the right design parameters to build the final product that is the concept design. The main objective of weight optimization is to build a concept design with less weight as compared to other designs. DEP (Detroit Engineered Products) has been one of the prevailing companies to give desired results to the customers in India and USA. Both countries have good amount of reputed automobile industries, hence weight optimization becomes an important practice to get designs which have less weight, use less material for manufacturing and ultimately reduction in cost of the design. Weight optimization is mainly linked to get the right material i.e. metals, which have superior qualities compared to other metals. The weight optimization method includes four stages, reference model then sim
