1. An air intake apparatus for supplying air to an internal combustion engine, comprising;
an enclosure that is hollow;
a motor vehicle battery;
an air filter;
an air compressor which when activated supplies compressed air to the engine, the enclosure housing the battery, the air filter and the air compressor; and
an engine air supply path through the enclosure that passes from an air inlet to the enclosure to an air outlet from the enclosure via the air filter, said enclosure inlet and enclosure outlet defining respectively an upstream end of the air supply path and a downstream end of the air supply path;
wherein the air intake apparatus includes an automatic air bypass within the enclosure that directs air in the air supply path to the air compressor when the air compressor is activated, and which allows air in the air supply path to bypass the air compressor when the air compressor is not activated.
2. The air intake apparatus of claim 1, in which the air bypass includes a passive valve that operates automatically depending on air pressure differences within the enclosure.
3. The air intake apparatus of claim 2, in which the passive valve is a flexible flap valve that is resiliently biased to a closed position, and which is pulled open under the action of air pressure in the air supply path when the air compressor is activated.
4. The air intake apparatus of claim 1, in which the air bypass includes a diffuser chamber into which bypassed air is admitted when the air compressor is not fully activated, the diffuser chamber having a diffuser outlet which mixes bypassed air and air expelled by the air compressor.
5. The air intake apparatus of claim 4, in which the diffuser chamber has an outlet aperture, and the air compressor has a compressor outlet that includes an outlet pipe that extends through the diffuser chamber, the outlet pipe having an exit that is surrounded by the outlet aperture with a gap extending around the outlet pipe exit and the outlet aperture.
6. The air intake apparatus of claim 5, in which the gap is an annular gap.
7. The air intake apparatus of claim 5, in which the outlet pipe exit and outlet aperture both have a circular cross-section.
8. The air intake apparatus of claim 5, in which the outlet aperture is the same as the air outlet to the enclosure.
9. The air intake apparatus of any claim 1, in which the enclosure is partly divided by a partition wall into a battery compartment and a compressor compartment, wherein the battery compartment houses the motor vehicle battery and the air compressor compartment houses both the air filter and the air compressor, and the air supply path extending through the partition wall.
10. The air intake apparatus of claim 9, in which the battery compartment is in the air supply path upstream of the air compressor compartment.
11. A motor vehicle, comprising an internal combustion engine for powering the vehicle and an air intake apparatus for aspirating the engine, wherein the air intake apparatus comprises:
an enclosure that is hollow;
a motor vehicle battery;
an air filter;
an air compressor which when activated supplies compressed air to the engine, the enclosure housing the battery, the air filter and the air compressor; and
an engine air supply path through the enclosure that passes from an air inlet to the enclosure to an air outlet from the enclosure via the air filter, said enclosure inlet and enclosure outlet defining respectively an upstream end of the air supply path and a downstream end of the air supply path;
wherein the air intake apparatus includes an automatic air bypass within the enclosure that directs air in tho air supply path to the air compressor when the air compressor is activated, and which allows air in the air supply path to bypass the air compressor when the air compressor is not activated.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A yogurt product that is frozen wherein:
the yogurt product comprising 50-100% fermented yogurt mix; and
the degree of overrun of the mix is between 20 to 150% by volume.
2. The product of claim 1, wherein the fermented yogurt mix comprises at least one component selected from the group consisting of dairy components, sweetening agent, fermenting microorganisms, stabilizer, water, and air.
3. The product according to claim 1, wherein the amount of total solids is 26 to 45% by weight.
4. The product according to claim 2, wherein the dairy component is selected from the group consisting of milk, cream and mixtures thereof.
5. The product according to claim 2, wherein the dairy components comprises fat in an amount of 0.5%-16% by weight.
6. The product according to claim 2, wherein the stabilizer is selected from the group consisting of starch, guar, gelatine, locust bean gum, xanthan gum, acacia gum, carageenan, pectin and tara gum.
7. The method according to claim 2, wherein the amount of stabilizers is 0.01-1.0% by weight.
8. The product according to claim 2, wherein the amount of sweetening agent is 5 to 20% by weight.
9. The product according to claim 1, wherein the mix contains no emulsifiers.
10. The product according to claim 1, wherein the pH of the final product is from 4.0 to 6.0.
11. The product according to claim 1, wherein the product can be consumed frozen or thawed.
12. A method for producing a yogurt product that is frozen comprising the steps of:
providing a yogurt mix comprising dairy components and at least one component selected from the group consisting of: sweetening agent, stabilizer and water;
blending the mix;
homogenizing the mix;
pasteurising the mix;
heating the mix to 65-85\xb0 C. for 15-40 min to denature proteins;
cooling down the mix to specific incubation temperature of the fermentation organism which is typically 37-45\xb0 C. and incubating with yogurt culture;
agitating and cooling the mix to or below 10\xb0 C.; and
between 3-10\xb0 C. feeding the mix through an ice-cream freezer to incorporate overrun.
