Fuel Savings for Mining
The TFS exhaust system is designed to improve engine performance and fuel efficiency while reducing emissions. It has been in development for over 3 years. It works by optimizing exhaust gas flow without any moving parts. Test results show increases in torque and horsepower of 20-30% and fuel savings of 15-25%. For large trucks and machines, the system can save over $50,000 per year in fuel costs.
Trucking: 15 to 25 Percent in Fuel Savings
We have the worldwide rights to sell a patented exhaust system. In a nutshell here is what it does:
* Creates a fuel savings of 15-25%
* Reduces emissions by up to 35%
* Increases engine torque by 20-30%
* Increases horsepower by 20%
1 GtechOverview
Global Technology has developed two patented technologies that can significantly reduce emissions and fuel consumption in combustion engines:
1. An engine modification that reduces fuel consumption by up to 70% while also lowering emissions. It has been independently tested and verified.
2. An exhaust system modification that reduces emissions to near-zero levels, barely measurable. It has also been independently tested.
These technologies surpass government emissions and fuel economy targets for 2025. They can be applied across multiple vehicle and engine markets. Global Technology believes these innovations provide an answer to increasing demand for lower emissions and greater efficiency.

Multicollinearity1
This document discusses multicollinearity in regression analysis. It defines multicollinearity as a near linear relationship between predictor variables, which violates an assumption of classical linear regression. It provides an example of multicollinearity between product price and competitor prices. The effects of multicollinearity include indeterminate regression coefficients and infinite variance and covariance of coefficients when multicollinearity is perfect. Sources of multicollinearity include the data collection method, constraints in the population, model specification, and having more predictors than observations.
Advanced Econometrics by Sajid Ali Khan Rawalakot: 0334-5439066
This document appears to be the introduction or table of contents to a textbook on advanced econometrics. It includes 10 chapters that cover topics such as simple linear regression, multiple linear regression, dummy variables, autocorrelation, and simultaneous equation systems. The introduction defines econometrics and discusses its goals of policy making, forecasting, and analyzing economic theories using quantitative methods. It also outlines the methodology of econometrics, which involves stating an economic theory, specifying mathematical and statistical models, collecting data, estimating parameters, testing hypotheses, forecasting, and using models for control or policy purposes.
Multicollinearity
This document discusses multicollinearity in econometrics. Multicollinearity occurs when there is a near-perfect linear relationship among independent variables. It can lead to unstable parameter estimates and high standard errors. Symptoms include high standard errors, unexpected parameter signs or magnitudes, and jointly significant but individually insignificant variables. Diagnosis involves examining variable correlations and testing joint significance. The variance inflation factor (VIF) measures the impact of multicollinearity, with values above 2 indicating a potential problem. Remedies include acquiring more data, dropping problematic variables, or reformulating the model, though these can introduce new issues. Multicollinearity alone does not invalidate estimates.
Multicolinearity
The document discusses multicollinearity in regression analysis. It defines multicollinearity as a statistical phenomenon where two or more predictor variables are highly correlated. The presence of multicollinearity can cause problems with estimating coefficients and interpreting results. The document outlines symptoms of multicollinearity, causes, consequences, detection methods, and remedial measures to address multicollinearity issues.

2010 hdeo trends 032010
Truck sales remain low as new emission standards require expensive upgrades to vehicles. Off-road engine sales are also low but expected to rebound as interim emission limits phase in. Emission regulations are driving the need for new lubricant specifications with improvements in areas like low SAPs and robustness to support extended oil drain intervals with modern aftertreatment devices. The global heavy-duty engine oil market is projected to increase overall with the fastest growth in Asia-Pacific countries and a shift toward higher performing multi-grade oils.
Toronto future directions - 2015
The document summarizes a presentation given by Lubrizol Corporation on industry trends related to efficiency and implications for lubricants.

An Observational Study of the Predictors of Mileage Per Gallon for a Car
- 2. Introduction • Approximately one half of the oil used in the U.S. is imported • Nearly $2 trillion was spent from 2004 to 2008 on oil • New Corporate Average Fuel Economy (CAFE) standards passed with goal of 35 mpg on average by 2020 • Decided to conduct a study on how we can reach this goal
- 3. ID MY MPG WT DISP HP ACC 46 1978 9.8 4000 258 125 14.2 47 1978 11.8 4409 315 149 13.7 48 1978 12.2 4500 338 159 13.1 49 1979 15.3 3026 180 128 12.2 50 1979 21.7 2450 113 77 14.4 51 1979 19.0 2847 155 94 14.2 52 1979 15.4 3624 246 117 14.4 Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends: 1975 Through 2011
- 4. Limitations Our Regressors Chosen • Weight • Engine displacement • Horsepower • Acceleration time Other factors not considered • Variable valve timing (5%) • Cylinder deactivation (7.5%) • Turbochargers and superchargers (7.5%) • Direct fuel injection (11-13%)
- 5. Initial Data Viewed problems of possible multicollinearity and non-linear relationships
- 6. Multicollinearity Variance Inflation Factors are close to or greater than 10 Condition Indices greater than 15
- 7. Autocorrelation Durbin-Watson statistic is very close to 2 After “normalizing” data
- 9. Power transformation Found best lambda Maximized Log- Likelihood and R- squared Applied the log function to DISP and HP
- 10. Residual Plots Residuals Before Transformation Residuals After Transformation
- 12. Ridge Regression to Reduce the Multicollinearity
- 13. Ridge Regression to Reduce the Multicollinearity
- 16. Future Work • Expanding the study with current data Bootstrap Confidence Intervals Add Variables Time Series • Conducting an experiment Sample Size Expand Predictors
