Abstract
A vehicle engine is provided that includes an exhaust manifold configured to emit a first emission. A heat shield is positioned proximate the exhaust manifold and has a shield substrate defining an aperture. An indicator is positioned over the aperture with a support substrate and a semiconductor layer. The semiconductor layer is configured to absorb the first emission and emit a second emission.
Claims20
A vehicle engine, comprising:
- an exhaust manifold configured to emit a first emission wavelength;
- a heat shield positioned to a side of and at a distance from;
- the exhaust manifold having a shield substrate defining an aperture;
- and
- an indicator positioned over the aperture and comprising:
- a support substrate;
- and
- a semiconductor layer configured to absorb the first emission wavelength and emit a second emission wavelength wherein the exhaust manifold and the indicator are separated only by ambient air.
