Living more healthily sounds like an obvious outcome of energy descent, or is it?

What are the implications (positive and negative) for our health and wellbeing, and what can we do to improve our health in a low carbon lifestyle? How can we ensure that everyone has access to affordable healthy food when peak makes imported food too expensive? How will the changes to people's lifestyles in the future improve or have a negative impact on their health? Here is the place to start, discuss these issues with others and we'll try get the ball rolling

Developing Diagnostic Auto Emissions, Using Exhaust Gas Analysis

Lambda is perfect air fuel ratio 14.7 parts of air to 1 part of fuel. The closer you get to Lambda, the less carbon emissions. Lambda is a great diagnostic tool, more fuel and less air means rich condition, which will cause the CO and HC gases to be high. We will discuss carbon emissions, and automotive energy efficiency further in this blog.


-Combustion efficiency speaks for itself, the more efficient the combustion is, the cleaner the emissions gases are and the better the fuel mileage is. For checking combustion on your vehicle, consult an auto repair technician with the proper equipment. Carbon Gases pollute the earths atmosphere and can cause a number of Ozone problems including Acid Rain. There are three very harmful gases, Carbon Monoxide, Hydrocarbons and Oxides of nitrogen.


-Carbon monoxide or (CO), this harmful gas will usually be out of range when there is a fuel problem and the vehicle is rich, considering it is a reading of unburned fuel or raw fuel escaping the tailpipe.


-Hydrocarbons or (HC), this gas is will be seen usually with an ignition problem. HC is read in parts per million or grams per mile. It is the reading of partially burned fuel escaping the tail pipe. Both of these carbon emission gases can be easily diagnosed, using the correct procedure and checks, including your Lambda Numbers.
